Short: V1.3 of a new C64 emulator, 68020+ only
Uploader: cbauer@mzdmza.zdv.uni-mainz.de (Christian Bauer)
Author: cebix@ng-box.wwb.sub.de (Christian Bauer)
Type: misc/emu
Third release of a new multitasking 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 is therefore not very fast (using a
68040/25 and a Piccolo card gives about half of the original C64 speed).
However, using a line-based VIC model, it is capable of running most
games and demos correctly, even those with FLI, FLD, DYCP, open
top/bottom borders, multiplexed sprites etc. (but not AFLI and other
effects depending on exact VIC/6510 synchronization).
EGS, Picasso and CyBERgraphics graphics cards are supported for faster
display. Using Amiga modes is possible, but slower (though there's a
very fast monochrome Amiga mode).
Some small demo programs and the full source code in assembly language
are included in the archive.
Changes from V1.0:
- Average graphics speed is now higher, especially in multicolor and
bitmap modes
- New, very fast monochrome mode
- Sprite routines are more efficient. No processor time is wasted
when all sprites are off.
- Sound emulation with 6581sid.library when SID card is disabled
- Minimal screen resolution is now 384╫272
- Sprite collisions can be turned off
- 1541 emulation now handles sequential files, wildcards and access
modes and ignores drive numbers and the '@'
- Frodo is now multilingual by means of "locale.library"
- Overscan resolutions can now be used
- Modes like PAL:Lowres are now selectable under OS2.x
- Option to translate '/' in file names to '\' and vice versa
- Joysticks are now only polled in the VIC vertical blank routine
- Amiga graphics routines now also use double buffering
- Option to accelerate the memory test on reset
- Bug in Close1541 corrected (could crash on quit)
- CyBERgraphics support
- Option to skip frames implemented
