- Atari 800, 800/XL, 130/XE and 5200 Emulator for the Amiga
- ---------------------------------------------------------
-
- Irrespective of whether you are going to compile the emulator yourself
- or install a pre-compiled binary version you must obtain a copy of the
- Operating System ROMs.
-
- The ROM images are distributed within the PC Xformer 2.5 package (other
- versions of this program do not contain the ROMs in a suitable format)
- which can be downloaded from:-
-
- Site: ftp.doc.ic.ac.uk
- Directory: /computing/systems/atari/umich/8bit/Xf2
- File: xf25.zip
-
- Note: Check your usual UMICH mirror first or do an archie search on
- xf25
-
- PC-Xformer contains "ataribas.rom", "atariosb.rom" and "atarixl.rom".
- If have the original OS it should be called "atariosa.rom" and if
- you have the ROM for the 5200 Games System it should be called
- "atari5200.rom".
-
- Notes
- -----
-
- 1. You need to install ixemul.library which can be found on AMINET.
-
- 2. It *does* work on Workbench 3.0 and *should* work on Workbench >= 2.0
-
- 3. The Amiga version is still running very slowly even on a 50MHz 030.
- This is because the emulator was written mainly for portability across
- Unix platforms using X11. The emulation of the Atari 800 custom chips
- is done entirely in software before passing the display to the Amiga
- specific code.
-
- AGA screen refreshing (i.e. chunky to planar) has been done in
- assembly, and hopefully I will find time to implement the 6502
- emulation this way as well.
-
- 4. The program was compiled on a 68030 + fpu based Amiga but I don't
- expect problems on other configurations.
-
- 5. There is a small bug in the program regarding the selection of
- disk images with the file selector - the program will ask you
- to insert a disk called the name of the file you selected. To
- avoid the problem you *must* select the file fully starting
- with the volume field, going down the directories and finally
- selecting the disk file (The full file path must be given).
- This doesn't affect anyone starting a disk file from the
- command line.
-
- Installation of the Emulator
- ----------------------------
-
- 1. Create a toplevel directory called "atari800" and a subdirectory
- called "object".
-
- makedir atari800
- makedir atari800/object
-
- 2. Copy the Atari800 LHA file into the newly create "atari800"
- directory and unarchive.
-
- lha x a800v060.lha
-
- 3. Copy the Operating System ROMS into "atari800/object"
-
- 4. Start the emulator by typing "atari800" while in the "atari800"
- directory.
-
- 5. Now that you've (hopefully) got the emulator running, you can move
- the executable and ROM files into a more convenient place. The
- ATARI_LIBRARY environment variable should be set to point to the
- directory where the ROM files are stored. If you can use Unix man
- pages you will probably want to install atari800 man page. Typically
- this involves copying atari800.man to /usr/local/man/man1/atari800.1
