I doubt that at the time PC's where not running at psx speed, probably you mean they werent powerful enough to emulate the playstation but in terms of cpu etc I think when bleem was released the PC had gotten ahead of the psx...Samor said:
The problem here with the speed up sound would be to isolate graphics, music fx, music and sound fx because you get alot of that in the emulator. It can be easily implemented but the sound effects would be behind, shoot something and the sound comes ten minutes later
