Here are some news about an upcomming release of PSX4iPhone from Zod:

– psx4iphone: This project is being worked on as you read this, though it’s a long process. It’s basically being rewritten from scratch by Hlide and I. It will introduce some unique techniques for squeezing extra performance out of the dynamic recompiler and emulation of devices such as the GPU, SPU, and CDROM interrupts. ETA: 2+ weeks
