Doesn't help most folks, but hopefully this will work from the loaders for those that care.
The new UMD emulator is seemingly running a bunch of new games. Midnight Club 3, for instance, works now. While it requires a 2gb stick (big game), loadtimes are supposed to have dropped from 60 seconds to around 8 seconds when starting a race. I've also heard that WE9 loads so fast on memory stick that it almost seems as if there is no loading at all (and overclocking removes the slowdown).
