At this time only a few firmware functions are known. Well, to be more exact, only a few are usable. While we know many of the functions provided by the firmware, we do not know many of thier arguments. At this time we know how to maniuplate the frame buffer, read button presses, read/write to the memory stick, and play back audio, but we do not have a way to control MMU mappings. We have only had the ability to write/execute code on the PSP for a month. Discoveries are being made all the time, so we will certainly know more about the firmware in the coming weeks.
