Ok, here is the deal. I'm trying to emulate all these systems.
Atari 2600
NES
TG-16
Genesis
SNES
Sega CD
Atari Jaguar
3D0
Sega 32X
Sega Saturn
Sony Playstation
N64
So far this is my results with these systems:
Atari 2600 - I actually haven't tried this emulator or the roms yet. Should be no problemo.
NES - I haven't tried this one either yet, again, it shouldn't be any problem
TG-16 - I have tried the Hugo with the TG-16 and it worked really well, but at the time that I had tried it, there wasn't any gamepad support. You had to use the keyboard. Maybe that has changed by now?
Genesis - I have tried my Genny emulator, and it works pretty damn good. Except sometimes it runs super super fast for some reason.
SNES - I have tried the SNES emulator and it works very good.
Sega CD - So far, I haven't been able to get Sega CD games to play. It's not recognizing my CD Drive or something.
Atari Jaguar - I did try Project Tempest, but I'm not getting anything? Maybe my PC is too slow. It's a PIII 866, with a G-Force MX card.
3DO - I tried FreeDO, but I can't get anything to work on this one either. I guess you need to play the games from the iso files, but I'm having some kindof a problem getting the iso files onto my PC properly.
Sega 32X - I've tried to play some 32X games on my emulator, but they have lots of problems. It basically crashes whenever I try it. I see the title screens of the games, but then the game doesn't run or has somekind of problem. Again, maybe my PC isn't fast enough.
Sega Saturn - From what I understand, there really isn't one decent Saturn Emulator out there that is actually worth a damn. At least none that works with any solid regularity with more than a small handfull of games.
Sony Playstation - I couldn't get any sound with ePSXe, but I could get EmuRayden to run fine.
Nintendo 64 - I have Project 64 and it works absolutely great!
So basically, to come to a conclusion, it appears that when it comes to the 3DO, Jaguar and Saturn, that maybe there aren't any really "SOLID" emu's out there for those systems yet. And when it comes to 32X, my PC might not be fast enough to run it properly. As for Sega CD, that's just me not being very good with my PC.
