Hi folks. I'm going to add some emulators on my iPhone, and I was wondering which ones simply are the best. I've seen several emulators for each system, and since some of them are paid apps I don't want to buy&try. Do you have any positive/negative experiences with any emulators? I've tried Snes9x which works great, and I also tried buying gpSphone (GBA emulator), but it only says "Recheck" at the top. Shoot!
