Plus the problem as to whether IS actually RUNS on the damned emu (Revelations works fine, but Eternal Problem is nigh unplayable, with serious slow down and the like).
Unfortunately, IS runs on emulator just like EP does, so it's pretty slow when there is a lot of text on screen, and battles can make it crash like a bitch. On the first matter, my new code for text rendering completely solves the slowdowns (which also happened in a similar manner on the Ps2), but still crashes in battle because the emulator is utterly bad. So, unless they don't fix the emulation core once and for all, you will have to play IS on a Psx, Ps2 or Pc emulator.
Well, at least I can use the Psp for some code testing, since no other emulator can detect those damn delay slots. :9
