> You seem remarkably confident for someone who has never taken one apart. Unless it would be very heavily restricted (rather a mmap-style thing than a real, direct MMU interface) it would be a serious security breach. OTOH if the assumption is that PSP is always running trusted code, it is possible that the game can influence the MMU and there are no security checks at all. I forgot that the whole ability of running untrusted code on 1.0 was a bug, and not something planned, so interfaces would not need be so tight. By the way, all PSPs you can buy now, except early Japanese version, are 1.5 or higher so the whole point of having a MMU interface is moot because, as of now, you can't run anything on it at all. Not even a hello world. Anyway, I'm going to take one apart :) Stanislaw
