Through my beta testing of psx4iphone I found a few things: If you hold R2 (the R button all the way on the right), then press either R1 or L1 (the inside L and R buttons), you will see a dialog come up and it will say "psx clock" along with a number. Pressing R1 increases it and L1 decreases it. I'm assuming this is you clock speed for the processor. I 'm not sure if this does anything, it may just be leftover from the original port. If you hold L2 and press R1 and L1, it will change your "PSX cycle". I don't really know what this means. And finally, if you press both L1 and R1, it will bring up a menu where you can change graphics and debug options. Along with savestates. I have only been able to navigate it once and when i hit save to savestate1, I cant navigate it anymore. It created a file in the roms folder with a .000 extensions and 0 bytes. So i don't think any of these work yet.
