Oh, well my idea was that maybe PSPSet and the default background selector thing on 2.0 were pretty much the same. I think I'm wrong though...I don't think SONY would allow such a program to flash the memory.
Well my idea was this. If the background feature on 2.0 and up was the same as PSPSet and flashed the memory, maybe there would be a way to encode some type of upgrade file onto an image file or find a loop hole in the background feature.
Once again, I doubt this could work. I just started thinking about it just now and I think it's impossible, sorry to waste your time. What a pointless idea.....
