Short: C64 emulator, V2.4
Author: cbauer@iphcip1.physik.uni-mainz.de (Christian Bauer)
Uploader: cbauer@iphcip1.physik.uni-mainz.de (Christian Bauer)
Version: 2.4
Type: misc/emu
Requires: AmigaOS 2.1, 68020
Frodo is a multitasking freeware C64 emulator for the Amiga and
DraCo. OS2.1 and a 68020 (or better) are required, as well as copies
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.
The "Graffiti" video card is also supported.
Some small demo programs and the full source code in C and assembly
language are included in the archive.
Changes from V2.3:
- The C64 Basic and kernal ROMs are now included in the archive
- FreeScreenBuffer() was called even under OS 2.x
- Corrected idle state display
- The last line of Y expanded sprites wasn't drawn
- Writing to $d011/$d012 can trigger raster IRQs
- Support for Graffiti video card
- Corrected translation of 0xc1..0xda characters in conv_from_64()
- 1541 emulation ignores drive numbers when opening the directory
and allows wildcards for selective directory reading
- Reading from a write-only SID register returns the last byte written
to the SID
- D2 and D3 were swapped in the SID card schematics
- Corrected ISB, RRA, SHX and SHY instructions
- Frodo SC: CIA timer one-shot mode didn't stop the timers
- Frodo SC: Corrected timing of CIA timers (starting/stopping/loading)
- Frodo SC: Fixed bug in BackECM
- Frodo SC: More undocumented opcodes implemented
- Czech catalog files
