I'd agree with that. Just because an exploit isn't known at this time doesn't mean it doesn't exist. The problem with sony endorsing homebrew is the legality behind it. It's a multi-billion dollar corporation, they know that the more PSP sales there are the more UMD games will be sold (math wise 1,500,000x3=4,500,000<2,500,000x2=5,000,000). Those numbers are fairly accurate. There have been 1.5Mil PSP's sold since launch, with an average of 3 UMD games per owner. I'm sure if you add sanctioned homebrew that would drop to an avg of 2 UMD games per owner, but with a MUCH higher volume of PSP's sold. So mathematically it would be in Sony's better interest to allow homebrew. The problem comes with corporate endorsing. If Sony endorses homebrew with the full knowledge that it can be used to run Nintendo emulators then they are endorsing Nintendo emulators and the pirating of Nintendo games in ROM form (mathematically agian 5,000,000-2,000,000,000 lawsuit=no more PSP). And not everyone hates Sony, they build great systems, but only for their intended use. The fact that the PSP can run homebrew at all is actually quite surprising. As far as I can figure only the PSP and the XBOX have this amount of homebrew, and the XBOX is basically a Linux console running DX7. So don't be mad at Sony for wanting to maintain control of the product they spent billions in R&D on, focus that energy into figuring out better ways to circumvent their authority. I still say there's got to be a way to make an EBOOT file that will be read as legit. I don't know how to do it, and I don't think I'll be the one to figure it out, but I still believe it's possible. And all we need is for it to recognize as a legitimate EBOOT for v1.0, then it will run on all firmware and the only way to stop it would be to recall EVERY game released for v1.0 and hand out updated copies. That wouldn't be economically viable. At that point Sony would have no choice but to accept homebrew on the PSP.
That's my rant for this evening, I'll be here till thursday, send your requests with your waiter.
