In answer to my and many other people's question about the possibility for a patch; I've just been playing Killzone Liberation and noticed that, (since May), there is a patch which can be downloaded from the games internal web browser, (an 8 Mb eboot), which gets copied onto your memory stick and installed:
Now this 'patch' may well just be an extension to the existing code base, where as a Wipeout Pulse bug fix may well be alot larger and more complicated. But at least a PSP 'patch' president has already been set
I imagine that a patch for encrypting that settings file which cheaters use and ensuring only clean times are uploaded onto the website could be a possibility, as the game engine wouldn't need much messing around with... Or I could just be talking a speculative load of bollocks?
