Well, I've been sceptical myself about all the emulators, until I saw GPEngine, later Frodo and finally Castaway coming to us...
The Genesis is a system comparable to the Atari ST (main processor: 68k).
The only problem is that the Genesis has an additional graphics processor, the Z80.
But that shouldn't take up too much processor power.
The Amiga, too, has an 68k processor, but a lot of additional custom chips.
That's why you even need a pretty fast PC to emulate it... in my opinion: not possible.
The SNES will be hard to emulate at full speed - I'm not really expecting one...
But if it gets even close to 100% I'm happy, since I mostly play RPGs where you don't need
a high framerate.
The GB/GBC/NES CAN be emulated full speed without any frameskip.
I think, the GBA CANNOT be emulated full speed... but, well, it's an actual system, I wouldn't want
one because it will be most likely be used for illegal reasons.
So, I guess all the emulators which would be interesting CAN be done!
Oh, and one final note to mangax:
I'm in the emulation scene since a long time.
In fact, the first emulator that I used has been A64 on an Amiga... that was 1991!
Since then I tried all the emulators I could get. I remember being baffled when I saw Zelda for the
SNES running on my 486 with about 1 fps.
And I even can remember the first version of Nesticle...
But I still say: There is no system 100% emulated! Most emulators for the PC today get probably a whopping
99%, but 100% is still impossible.
I can't remember exactly which games, but I'm pretty sure I have some ROMS which don't work on any
emulator.
I still remember Star Tropics 2 for the NES. This game is only playable since last year (with Nester being the
first emulator running that game), and that's about six years after the NES emulation scene started...
So, give the emulation scene for the GP32 six years and see what'll it become...
