- Short: C64 emulator, V2.0
- Uploader: bauec002@goofy.zdv.uni-mainz.de (Christian Bauer)
- Author: bauec002@goofy.zdv.uni-mainz.de (Christian Bauer)
- Type: misc/emu
- Replaces: misc/emu/FrodoV1_5.lha
- Version: 2.0
- Requires: AmigaOS 2.1, 68020
-
- Frodo is a multitasking freeware C64 emulator for the Amiga.
- OS2.1 and a 68020 (or better) are required, as well as copys of
- the original C64 ROMs, which are not included.
-
- This emulator focuses on the exact reproduction of special graphical
- effects possible on the 64, and has therefore relatively high system
- requirements. Using a 68060-50 and a CyberVision card gives about
- 140-160% of the original C64 speed in standard text mode in the
- emulation's most precise mode and about 700% in its fastest mode.
-
- Using a line-based VIC model, Frodo is capable of running most games
- and demos correctly, even those with FLI, FLD, DYCP, open top/bottom
- borders, multiplexed sprites etc. A single-cycle version of the
- emulator, "Frodo SC", is included that runs even those programs that
- fail on the line-based emulation.
-
- A graphics card (any one whose modes are selectable with a screenmode
- requester will do) is strongly recommended for faster display as the
- emulator's routines have been designed for a chunky display memory.
-
- Some small demo programs and the full source code in C and assembly
- language are included in the archive.
-
- Changes from V1.5:
- - Completely new graphics handling, removed all graphics card specific
- code
- - More precise emulation of the DEN bit in register $d011
- - Small optimizations to the VIC and 6510 routines
- - On startup the RAM is initialized (almost) like on the real C64
- - 100% correct ADC/SBC in decimal mode
- - Better emulation of addresses 0 and 1
- - Better NMI triggering
- - Fixed CIA interrupt handling
- - Pressing F9 could cause pending interrupts to be lost
- - 1541 Open routine checks for file name buffer overflow
- - Closing 1541 channel 15 closes all open files
- - Read-only .d64 and x64 disk image file support
- - Four types of SID emulation: None, the SID card, 6581sid.library
- and playsid.library
- - Menus for the prefs window and the emulation window
- - Loadable/saveable preferences, prefs files are Frodo's "projects"
- - Integrated assembler/monitor (SAM)
- - Speedometer and speed limiter
- - Corrected the SID card schematics and included a DeliTracker player
- module for the card
- - Includes Frodo SC
