    vbt,

    of course there is. Both projects should be developed as a branch, though.

    Just wondering if it might be possible to have a chat about FAZE sometime soon. I really think this is the right time to get back to it cause Gens is having some issues with it and we have to merge your changes with my current source.

    Regards.

    It would need FAME and FAZE, not sure it would be enough to run a MD emu at full speed on Saturn.
    I know for sure that SEGA of Japan did program a Mega Drive emulator for Saturn. If you check the Sega Ages Disney Collection feat. Quack Shot and Castle of Illusion, you will notice that Castle of Illusion is a regular Mega Drive ROM that can be run in any emulator like Gens or Kega. They apparently used variants of this emulator in the Thunder Force Gold Packs, the Phantasy Star Collection, and Sonic Jam.
    I'm not sure it was emulators.
    - If you were to use FAZE to emulate the Z80 at a very, very low underclocked rate, and use the Saturn's M68000 to emulate the Mega Drive's CPU, I think you could get it up to a playable speed.
    Sound and video emulation would still be a problem...
    I would be worth to try with FAZE & FAME, I don't really see how to use the Saturn 68k to run the 68k MD opcodes.

    Well, most if not all of the existing Mega Drive emulator variants that Sega of Japan used, do use streamed ADPCM, or even CDDA (Thunder Force Gold Pack 1), instead of FM sound emulation. But there seem to be Mega Drive ROM dumps on all the released CDs. Some are split into two or three parts though, while Castle of Illusion is just a plain Mega Drive ROM that works in Gens or Kega.





    The .BIN file is the actual ROM, the .ADP files is the ADPCM encoded soundtrack.

    I have no idea, really, but apparently that's what they did at Sega of Japan. That would also explain why there is no FM emulation / simulation: They needed the 68k to emulate the Mega Drive's CPU.

    Me neither. - Could you estimate how much of the Saturn's hardware capacity is used by SMSplus ? Is there room to gain speed by using the second VDP or second SH2 ?
