Honestly. Freedo is cool because it's a 3do emulator (obviously), but it just sucks it certain ways. The graphic reproduction is great but the sound is so damn bad... ear splittingly bad. I just can't play anything on it, sound is such a large part of the 3do experience. No joystick support either. Progress on it is slow but how much can you ask of guys to do this in their spare time. As far as ISO files... google is friend.
I think, that the graphic reproduction is better in another 3DO emulator - FreeDO Phoenix 35.1.
and if you want a good sound in games - you need a good computer (non 2 core), cause in some test old Athlon is better than a GOOD new machine.
for example - i have no problem with sound (AMD Athlon 1.7, 512 mb.) grafic card is not important, cause emulator doesn't use open GL for now.
and what about games.... I don't understand - why not to help, and give a man some links? In my forum we have a big thread with link. And there are some forums that specialize on link with games.
