Changes in this Document =========================== There is no changes in this doc from the one in v0.42, except for a few words about a new monitor command: PATCH 1. Introduction =============== This is the second try of an useful documentation, I'm not good at that... Please *do* read it. 1.1 What is PaCifiST? --------------------- PaCifiST is an Atari ST emulator for PC. This is a SOFTWARE emulator, meaning you don't need a specific extension card with ST components, just your PC. This allows you to run many Atari programs on your PC. 1.2 Why should you use it? -------------------------- If you were an Atari ST owner, the answer is: Nostalgia! It is really cool to be able to run your old programs. Nowadays, there are tons of multi-megabytes games for PC, with incredible graphics & unbelievable sounds, but except for a very few, they are boring, and have no "spirit"... The Atari is not the only machine with great games (I also enjoy C64 & Amiga), but if you have ever played with Super Sprint, Stunt Car Racer, Dungeon Master, Colonial Conquest... I think you get the picture of what GOOD games are. Of course, there are not only games on Atari ST! It was widely used by professional musicians for instance, and about all kind of programs exist. 1.3 Features ------------ PaCifiST emulates the following components of the original Atari ST: Motorola 68000 The 68000 emulation is written in 100% assembly language. All aspects of the processor are respected except for BCD instructions (not correct). Prefetch can now be emulated, using "pref" command in monitor. Because it slows down the whole emulation, you should only use this to bypass tricky routines. Shifter (Video) The 3 standard ST graphics mode are supported. You can choose between a monochrome (hires mode) or a color (lores & medres) emulation. All video emulation is also performed in 100% assembly language. Some special tricks (palette switching, rasters) are handled, provided you use a VBE2.0 driver and toggle the "LINE" video-building mode. At this time, overscans and "syncscrolls" are NOT supported. 6301 (Keyboard) A genuine Atari uses this processor for keyboard, mouse, joystick & clock control. The exact behavior of this chip is not emulated (It is much too time- consuming) but the simulation is better and more accurate with each new version of the emulator. A mouse is needed. If there is no joystick connected to the PC (or you have disabled it in the INI file), a keyboard emulation is proposed. YM-2149 (Sound) This soundchip is emulated if a supported soundcard is detected (SB only!). This part is written by Arnaud Carre. Since v0.41, I've started STF samples emulation. MFP (Interrupts) VBL, FDC, ACIA, TIMER C are correct, as well as TIMERs A, B & D in events count mode. HBL is not very accurate, but on a mere ST it's almost the same. FDC / HDC PaCifiST uses 3 levels of disk emulation: Gemdos, BIOS and hardware level. The Gemdos level allows you to use all your harddisks space under emulation. For BIOS & hardware level, disk images are used to reflect real Atari ST floppy disks contents. Since v0.42, you can also use the PC floppy drive (A:) BUT USE IT AT YOUR OWN RISK! I/O Output to Parallel are sent to LPT1:, the serial is not functional at this time, and there is NO midi. 1.4 Future Plans ---------------- There are many things left to do, as well as many things to fix. The "to do" list is as follows, in no particular order. - better STF samples - fix the buckets of remaining bugs - STE Blitter & DMA sound [in progress] - support for more soundcards - boost the 68000 a little more (I've one idea or two...) B-) - support for two joysticks, two mice... - overscans & syncscrolls - stronger monitor (evaluator, conditional breakpoints...) - working serial communication - Better FDC emulation (many programs don't load yet) - on-the-fly TOS change, monochrome selection - Atari<->PC transfer program - non-VBE2.0 line-mode support - a freeze/reload memory option Write me if you want another feature... Other neat features would be: - native 6301 emulation - Midi support - FDC-level emulation in PC drives A: & B: (no chances!) But I haven't got enough docs (nor courage!) at this time. 1.5 How much does it cost? -------------------------- Well, technically this program is FREEWARE. Even if I keep the rights on it, you are free and encouraged to spread it around you, provided you don't charge for this. Please read this ALSO: ==== ...BUT you are highly encouraged ^_^; to contribute. I spend almost all daytime on this project and I'd be really glad to receive any kind of reward for it. Sending me a few amount of money would be very kind, and will perhaps allow me to bye a Modem and pay the phone bills. If not, you can send me a postcard, an old sci-fi movie [Ed.Wood...], a home-made CD or...a local beer! I HATE crippled shareware programs, I don't want to do this: In return I hope those who can afford it will send some money. 2. Installation =============== 2.1 Requirements ---------------- PaCifiST is designed to be run in a DOS environment. It works best under plain DOS, but will be happy in a box under Windows 3.11 or 95. I don't know for other version or DosEmu. The MINIMAL configuration you should run this program under is a 486DX-100. It will work with less, but don't expect it to be pleasant. I develop PaCifiST on an AMD 586-133 (about a P75 power), and the speed is almost always >= 8Mhz Atari ST at FULL FRAME RATE with sound enabled, under most games. Of course if you run a plasma routine with lots of color change, it will be slowed down... PaCifiST takes about 1.5Mb of memory itself, add to this the amount of ST RAM you want to have under emulation. With 8Mb of memory for instance, you can emulate a 6Mb Atari. A mouse is NEEDED. You can choose between the built-in mouse interrupt (SERIAL mouse in COM1 or COM2 only) or a mouse driver you have loaded before. The built-in driver doesn't work under windows 95. It is just a try to fix MANY mice-crashes encountered by several persons. If PaCifiST doesn't detect a joystick, it will use the numeric pad (with NumLock off) to simulate one. You can enable the joystick emulation with F4 under monitor. A Soundblaster compatible card is needed if you want to hear something. Apart from these requirements, you need a dump of an Atari ST TOS (The ROM). If you can have at least 2 different TOS versions, you all likely to run more programq, because PaCifiST has different problems with each TOS version. Run the ST program DUMP_TOS.PRG (in STFILES directory) to extract a TOS to disk. PaCifiST must be executed from its directory, which MUST contain PACIFIST.INI (the configuration ASCII file) and PATCH.H68 (some 68000 code needed to use mounted directories). 2.2 PaCifiST Concepts --------------------- This section explains some concepts you must understand to figure out how to configure the emulator options. 2.2.1 A word about the Monitor ------------------------------ By default, when you run PaCifiST, you start in the MONITOR screen. In order to run the emulation, you must type "g" (go) and press enter. You can go back to this screen at any time by typing in the key under ESC and above TAB. You may want to do this to quit, reset the Atari, Choose a video Mode or a Speed mode... IMPORTANT: Sometimes, when you come to the Monitor Screen, nothing you type on the keyboard will appear. Just press CTRL, SHIFT and ALT to clear the problem. When the 68000 hangs (bombs...) it is possible that the monitor does not show when you press the hotkey: Just wait a few seconds. Read the Monitor Commands Summary section for more information. 2.2.2 Video Emulation --------------------- There are 2 different video emulation methods available under the emulator. This only concerns the standard low resolution Atari video mode. The first mode (and default) is called the "Screen-Oriented" mode, because all the Atari screen is generated in a single pass. It means you can only have one palette (16 colors) for the whole screen, and no special effects. This is the mode you must use to run Gem applications, because it is faster. The second mode is called "Line-Oriented" mode, and this time, each line of the ST screen is processed separately. This is the mode you should select to run some games and most demos. Screen-Oriented mode: - don't allow any video tricks + works well under Windows (even windowed) + fast + work on all PC Line-Oriented mode: - slower - need a VBE2.0 driver - don't work well for some games/demos - works ONLY in full screen under Windows + several video modes (320x200, 640x480...) available + able to emulate palette switching, rasters... You can switch from one mode to another easily whenever you want. IMPORTANT: Line-Oriented mode don't work in hires/medres. 2.2.3 Speed Modes ----------------- Since v0.4, there are two different speed modes: ST and MAX mode. The default mode is ST-speed: Even with the fastest Pentium-class machine, you won't exceed the speed of a genuine 8Mhz Atari ST: This is necessary for some programs to run properly. The other mode, MAX-Speed will synchronize the emulation to the PC speed. This is fine for all system-compliant applications, but MANY programs won't work in this mode. It is NOT RECOMMENDED to change mode while running a program, it may crash. Change, BEFORE entering emulation. 2.2.4 Drives Emulation ---------------------- PaCifiST provides you three ways to emulate ST drives: - PC DRIVE A: I made this because of MANY requests. This is REALLY NOT RECOMMENDED!!! There are still many problems with disk changing and write-protection handling. If the <pcdrive> directive is enabled at startup and there are no images selected for disk A:, then PaCifiST will boot on disk. This should work with some games, but PLEASE DO USE IMAGES INSTEAD... ^_^; Please repeat: "I know that protected disks won't work. I shall *not* flame Frederic." - DISK IMAGES: This is a file that contains all the sectors of a given disks. For the emulated Atari, they are similar to physical disks inserted in drives A: & B:. Disk images work for all programs, even those that directly use the disk controller. You can choose two disk images at startup with the "IMAGE=" directive, or during the emulation under the DISK SELECTION screen. Since v0.41, PaCifiST is also able to directly use MSA files. - MOUNTED DIRECTORIES: This only works for programs that use Gemdos for file access, and there are still some compatibility problems with file-selectors and shell programs. This allows you to mount any directory as an Atari unit. For instance, if you mount "D:\ATARI" on the Atari C: at startup, the emulated machine will see this directory and its subdirectories as its C: drive. You CAN mount a whole partition, but it is NOT RECOMMENDED. You might put all your Atari stuffs in a directory or two, and mount them as units. This way, even if a big crash occurs, your PC system files won't be affected. You can't change the mounted directories on the fly, you must restart the emulator to do so. 2.2.5 Sound ----------- Only Soundblaster compatible cards are supported in v0.4. PaCifiST won't try to autodetect the settings by itself, but rely on the BLASTER environment variable. Before running the emulator, be sure it is properly set. Read your soundcard documentation if you don't manage, but if you know for sure the settings, type under DOS: SET BLASTER= Axxx Ix Dx where Axxx is the Port value. By example A220 where Ix is the Irq number. By example I7 where Dx is the DMA channel. By example D1 The STF samples are really bad at this time (it also depends on the replayer). You can disable this emulation in the INI file. You can switch this feature with F5 under monitor. 2.3 Before running it... ------------------------ PaCifiST is configured through a normal ASCII file: "PACIFIST.INI". You can edit it with any file editor to change the default behavior of the emulator. Some options can be overridden easily with commandline switches. This document contains a section which explains all the options. Please keep a copy of the original INI file, in case you made something wrong. The first time you will run PaCifiST, there are a few things that must be adjusted that depend of your system. The most important thing is to indicate PaCifiST where to find your TOS image, and at what memory location to load it. Note the size of your TOS file, load the INI file and go to the [system] section. Sections are just intended to group directives by topics. You can comment lines with ";". All text after this will be ignored. tos= is the directive that gives the TOS file name. tosbase= is the directive that gives the TOS memory location. Say your TOS file, called TOS.IMG or whatever, is 192Kb (196,608 bytes). It is likely to be version 1.0, which address is 0xfc0000. In this case, you must put in the ini file: tos= tos.img ;you must specify the path if the file is not in the ;PaCifiST directory. tosbase=0xfc0000 ;location for TOS1.0 If your TOS file is 256Kb (262,144 bytes), you're sure the address is 0xe00000. tos= tos.img tosbase=0xe00000 IMPORTANT: If several TOS or TOSBASE directives are in the INI file, it is the last ones that will be take into consideration by the emulator. It is the same for all directives, apart from IMAGE & MOUNT. The default INI file that comes with PaCifiST contain some sample of TOS configuration. You must also be sure that the path specified for all MOUNT directives are valid. If you're unsure of understanding these MOUNT things, just comment the lines (put ";" before the directives) and read the INI directives reference. 3. Configuration ================ There are 3 levels of configuration. The INI files contains global options, while command line switches affect only the current session. Some options can also be changed on the fly. 3.1 INI directives reference ---------------------------- all tabs, spaces and texts after ';' are ignored. 3.1.1 System Section -------------------- TOS = <file> Name of the TOS dump file TOSBASE = <adr> Address of the TOS in memory (0xfc0000 for 1.0, 0xe00000 for other versions) AUTORUN = [yes|no] If YES, PaCifiST will jump into emulation when you run it, skipping the monitor screen. RAMSIZE = <n> Specify the RAM amount to emulate in megabytes. This is a number from 1 to 14. SOUND = [yes|no] Indicates whether or not you want sound. SAMPLES = [yes|no] Do you want *bad* STF samples? VOLUME = <n> Indicates the sound volume. Maximum is 255, and is the default value as you probably will prefer to adjust the sound level externally. INTERNALMOUSE=[yes|no] default is no, and tell PaCifiST to use the normal mouse driver given by DOS or Windows. If you have encounter problems with a serial mouse, try "YES" telling the emulator to use its built-in serial handler (not under Win95). SENSITIVITY=[1-10] Mouse sensitivity (only with external driver). Default is 5. MOUSECOM = [1|2] this works with the INTERNALMOUSE directive and indicates on which Com port is your mouse. SERIAL = [yes|no] Disable/enable the serial port emulation. Still buggy anyway. Try no if PaCifiST hangs. JOYSTICK = [yes|no] If disabled, no joystick will be used, but instead an emulation with the numeric pad. LEDS = [yes|no] Default is yes. If disabled, no LEDs blinking will be done. IMAGE = <file> This directive gives the name of a file (disk image) to be "inserted" in drive A: & B:. You can put two IMAGE directives in your INI file. MOUNT = <absolute path> Indicates to mount the given path (by example C:\PACIFIST\STFILES) to an Atari unit. The first one will be drive C:, you can specify 24 different locations. The specified PATH must be ABSOLUTE, with the letter indicated. PCDRIVE = [yes|no] Default is no - Should PaCifiST use the PC Drive A:? Enabling this feature adds an item in the diskselection screen. 3.1.2 Screen Section -------------------- MONOCHROME = [yes|no] Don't you guess? It has something to do with colors... FASTVIDEO = [yes|no] If you choose YES, PaCifiST will only convert modified portions of video memory. This is only used in the Screen-Oriented mode. If your graphics card is very fast, you don't need this option. REFRESHRATE = <n> The default value is 1, meaning that EVERY Atari screen is converted to the PC screen. Try a bigger value if the emulation is too slow on your PC. If you choose 3, only a screen out of 3 is displayed. 3.1.3 Debug Section ------------------- This is only useful for beta-testers and those who want to examine PaCifiST's behavior, watch interrupts, FDC emulation, mouse events... You need to have a "debug" distribution of PaCifiST for this. LOGFILE = <file> Name of the logfile, where all the information is written into. TRAPIRQ = [all|none|v] tell PaCifiST to stop execution when the given exception occurs. Default is none. If v is positive, it will be added in the list, if it is negative it will be removed from the TRAP list. You can specify several exceptions, separated with comas. LOGIRQ = [all|none|v] same as above, but this won't stop the 68000 but write information about the exception in the logfile. 3.1.4 PACIFIST.INI example -------------------------- [system] tos = c:\pacifist\tos.rom tosbase= 0xe00000 ;tos image=c:\pacifist\disks\boot.st ;name of disk image for Atari A: mount=c:\pacifist\stfiles ;C:\PACIFIST\STFILES will be Atari C: mount=c:\pacifist\games ;C:\PACIFIST\GAMES will be Atari D: autorun = yes ; jump directly to emulation mode pcdrive=no ; :) [video] refreshrate = 2 ;only render one screen out of 2. monochrome = no ;emulate an Atari with color monitor [debug] ; only with DEBUG compiled PACIFIST logfile = f:\debug.out ; the logfile for debug logirq = none ; erase the LOG irq lists logirq = 0x21 ; log GEMDOS calls logirq = 0x1c,69 ; log VBL & timer C too trapirq = 5 ; Monitor zero divide exceptions 3.2 Command line parameters --------------------------- Some INI directives can be overridden on the command line. Valid options are: /[h(elp)|?] list of options /refreshrate n same of REFRESHRATE directive /mono [yes|no] same as MONOCHROME directive /autorun [yes|no] same as AUTORUN directive /ramsize n same as RAMSIZE directive /sound [yes|no] same as SOUND directive /image <filename> Mount an Image BEFORE those in INI file /mount <path> Mount a Path BEFORE those in INI file /line Start in line-oriented mode (not recommended) /maxspeed Start in maxspeed mode (not recommended) /pcdrive [yes|no] same as PCDRIVE directive 3.3 Configuration under Monitor ------------------------------- Read the Monitor reference section for a complete description of all the commands. If you don't know 68000, the only commands you need are: g go into emulation mode x quit to DOS vol <n> set the volume (0-255) help some help. Yes. Useful keys: [F1] switch from SCREEN mode to LINE mode. You need a VBE2.0 driver in order to be able to have the LINE method. [F2] Choose a video mode in the list. 256 colors mode don't work always, but are faster than 32K & 64K colors mode. [F3] Change from ST speed mode to the MAXimum speed mode. Do this BEFORE going into emulation. [F4] Enable/Disable the Joystick Emulation with keys. Numeric Pad & CTRL (with NumLock off) are used to simulation movements and fire. [F5] Enable/Disable the samples emulation. [F12] Display the DISK SELECTION screen. Can also be called during emulation. 3.4 The Disk Selection Screen ----------------------------- Use F12 at any time for this disk-selection screen. It can be useful to switch between 2 disks (in a multi-disks game...). I wrote the same kind of interface that Ulrich Doewich does for the Amstrad emulator CPE. It is pretty self-explaining. The file selector doesn't display all files, only .ST, .MSA .ZIP and directories, as well as all valid units. Use <ESC> to exit the screen. <UP>, <DOWN>, <PAGEUP>, <PAGEDOWN>, <END>, <HOME> to navigate in the file selector. <TAB> <LEFT> <RIGHT> choose disk A or disk B. <ENTER> will insert the selected image disk for the current drive. There is an item in the list to remove the disk. Of course, if the changed disk need to be booted (for a game to start...), you must also perform a reset (Ctrl-Break). Since v0.4, the fileselector will consider .ZIP as normal directories, you can then group disk images in such archives. This is still *experimental*. In order to extract files from archives, PKUNZIP.EXE must be in the PATH. files will be extracted in the TEMP directory if this environment variable exists, or in the PACIFIST directory. The temporary files are called PCSTIMG*.TMP. They are not erased when you quit the emulator (in case you want to keep the changes in it). Since v0.42, if the PCDRIVE directive is enabled, you can also choose the PC drive A: to emulate a real ST drive. IMPORTANT: Changes in the extracted disk image WON'T BE reflected in the original archive file! It is the same with .MSA files, because they are converted to .ST file. 4. Miscellaneous ================ 4.1 Hints --------- - DO NOT USE ANY WRITE-DELAYED DISK CACHING ("smartdrv c+"...) - some GEMDOS function are not well-emulated. for instance, with mounted drives, GFABASIC file selector is trashy (OK with images). - If you're having problems with PaCifiST configuration, you can try a front-end utility: If you run PaCifiST from DOS, there is AssiST, coded by Aengus Jankowsky. For Win95 users, there is PaCiLOAD done by Andrew Knipe. - If you have enough memory, when debugging, put the logfile in a ramdisk. - avoid using PCDRIVE. It is slow, unstable and less powerfull than images. 4.2 VBE2.0 ---------- In order to enable the LINE-building mode and emulate raster effects, you need to install a VBE2.0 driver in memory before running PaCifiST. Perhaps there is such a driver provided in you graphics card package? A very good choice is to have Scitech's Display Doctor. You can download this shareware version on their web page http://www.scitechsoft.com. 4.3 Disk Images --------------- These images just contain all the sectors put together in logical order: for all TRACKS x all SIDES x all SECTORS, there is a 512 bytes block. PaCifiST don't need any special information, because disk parameters can be read on the boot sector. If values seem wrong, PaCifiST tries to deduce it from the image file size. You can create your own images from your ST disks with the little utility IMGBUILD. It permits also to make blank images of standard or non-standard sizes. Read the RESOURCES section to see where to find it. Alternatively, PaCifiST is also able to use MSA file, but in read only. 4.4 Keyboard Mapping -------------------- Since v0.41, the keyboard mapping is similar to the Atari's, except that: - HELP is mapped on PageUp - UNDO is mapped on PageDown - CTRL+Break performs a reset (add SHIFT if the reset vector is trapped by the current program) - If NumLock is on, the Numeric Pad is the same as on Atari, else it is used for the joystick emulation (CTRL is fire). Also, F12 brings up the disk selection screen, and the key under ESC aborts the emulation and skips to the monitor. 5. The Monitor ============== 5.1 Monitor Screen ------------------ The blue bar at the topmost contains a reminder of useful function keys as well as current video-building mode & speed-mode. Right under, a display of the 68000 registers as well as an estimated relative speed and a (not accurate) rasterline counter. On the right: Current Stack (USP or SSP) dump, a list of the breakpoints, breakaccesses & the breakopcode values. The upper windows always show the 68000 instructions around the current PC location. a "*" right before an instruction indicates a breakpoint. You can use CTRL-Z to step into or CTRL-T to trace over, like in the good old MONST2! CTRL-U can be used to trace in trace-mode, without entering the TRACE exception (but of course executing it!) CTRL-G is an alternative for the <g> command. 5.2 Monitor Commands -------------------- Many commands need a "DEBUG" compilation of PaCifiST. Because this slows down the emulation, it is not included in normal distribution of the emulator, but you can find such a version easily: just read the RESOURCES section to see where are the PaCifiST support sites. Arguments between parenthesis are optional. Most values in the monitor are hexadecimal numbers. h,help,? Quick summary t Trace over. This traces all instructions except for BSR, JSR & TRAP, which are executed till they return. Hit any key to abort if the execution seems in a long loop. z (n) single step. If an IRQ or an exception (Bus Error,...) occurs just after, it will be triggered. This can be annoying with Timers in some programs. TRACE MODE can be traced d (adr) dump a disassembling on a few lines. g (n) go. You can specify a number of rasterlines. m (adr) dump memory (hexa & ascii). bp (adr) Add or remove a breakpoint. A breakpoint doesn't consist in a special opcode, the memory isn't changed but the PC is checked all the time. You can then put breakpoint BEFORE a program is loaded. Breakpoints don't always work when they are on the first instruction of an Exception routine (use TRAP in this case) ba (adr) Add or remove a breakaccess. Any read or write (hopefully) to the given location will break execution. Be careful: A word access at $10000 will do nothing with a breakaccess at $10001. bo <msk> <cmp> set the "break opcode". There can be only one! All opcodes are ANDed with the mask and compared to the second parameter. For instance "bo ffff 4e75" will make the execution stop after all RTS. To remove the breakopcode, enter something like "bo 1 0". s reg=<value> Set any 68000 register to a given value. s [adr]=<bytes> change memory (even ROM). Use "s [1230] = 4e 71 4e 71" to nop a longword instruction. Each bytes must be separated by spaces. nop <adr> <n> fill memory at <adr> with <n> NOPs... :) lb <file> <adr> (size) load a file (or part of it) in memory. sb <file> <adr> <size> save a part of memory to disk. reset (hard) Perform a reset. trap (vector) This command enables you to break execution each time a given exception occurs. Type TRAP alone for a list of the main vectors. animate <n> This will single step n instructions, with a dump of all the registers in the logfile after each of them. status Show some information about MFP & ST drives. disa <start> <end> Disassemble a part of memory in the logfile. FAST! kbd (bytes) Display/Put values in the internal 6301 keyboard buffer. vol (volume) Set the volume from 0 to 255 (dec), or display current value. x eXit. pref [on|off] If on, the 68000 prefetch queue will be emulated. Use this only when necessary because the emulation is slower in this mode. You can single step over prefetch queue, even if an opcode is changed. patch [off|...] Change the behaviour of PaCifiST in order to run more programs. the only patch at this time is for for Carrier Command. Type "patch cc" BEFORE the menu screen to fix the mouse. 6. Resources & Acknowledgments =============================== 6.1 Related programs -------------------- 6.1.1 Other Emulators --------------------- This only covers Atari ST emulation for PC. Refer to the comp.emulators.misc FAQ for more information. - STonX Written by Marinos Yannikos(nino@complang.tuwien.ac.at) It's a free emulator for Unix which comes with sources. A DOS version now also exists, ported by Dirk Jansen. The official website is: http://www.complang.tuwien.ac.at/nino/home.html - STEmu Written by Jochen Frank (uk9a@rz.uni-karlsruhe.de) is a new ST emulator. You can find it on Node 99. The first version I saw (0.2) works with TOS1.62, but the MFP was not yet implemented. - Gemulator 96 It is a COMMERCIAL emulator. It is faster than PaCifisT but can only run 100% system-compliant apps. Gemulator Classic is an older (but free) DOS version. A demo version exists: http://www.emulators.com 6.1.2 Utilities --------------- AssiST - who: Aengus Jankowsky (ajankows@iol.ie) where: http://www.iol.ie/~ajankows/st/pacifist.html A DOS front-end configuration program for PaCifiST. This program is very convenient to set up your .INI file. It's not only recommended for beginners, but for all users! PaCiLOAD - who: Andrew Knipe (alk@bluesky.net.au) where : http://www.labyrinth.net.au/~contact/paciload.zip A Windows front-end interface for PaCifiST. Easy to use, can also convert MSA to ST file before running the emulator. MSAtoST - who: Damien Burke (st@jetman.demon.co.uk) where: http://www.jetman.demon.co.uk/st/index.html A converter to translate MSA files to ST files (the disk image format used in PaCifiST). Many programs you may find on the Internet (Umich archive...) are in MSA format. PaCifiST can *now* deal internaly with MSA file, but in read only.
