WinVice, as many of you know, has the capability of recording movies and rerecording. It records sound and video (but still has to played back with a ROM and the emulator.) There's a few problems: no frame advance, and only 1 savestate slot (the last time I checked.) It can be used to make basic TASes, but has a long way to go before it can be accepted. Any thoughts?

If it's open-source, it should be possible to add frame-advance and more save state slots, right? If I recall correctly, the main problem with C64 emulation was that it was difficult to verify the ROM was good. I don't know how crippling that is of a problem, but neither do I know how to fix this. Still, I'd love to see C64 TASing become possible at some point. (And all other Home computers for that matter)

Adding frame advance to VICE isn't that difficult, I've done it before. The biggest problem about C64 are "roms". If you're lucky you can get one of the following: * ROM image of cartridge (.crt) (only ~50 games ever released on crt IIRC) * Binary disk or tape image of unprotected game (.d64 or .t64) (usually magazine disks/tapes) Then there are raw disk and tape images (.g64 or .tap) that can store protected games but for technical reasons there's no unique way for creating such a file from a medium, causing loading time differences. The majority of downloadable games are cracked with a prepended intro and modifications to the game code. I don't like TASing such games for obvious reasons. (Even "remember" modify game code to the point that even without cheats there are timing differences) As a compromise one might at least for games that don't load data from disk create a memory image at the moment control is transferred to the game itself and use that for TASing.
