I guess everyone here must use PSP-1000 models, 'cause I could swear the 1.50 kernel doesn't work on slims. Second, I never really used the game categories plugin (never figured out how to use it), so I can deal, third, if you're talking about the Game Boy Advance emulator, the newest gPSP mod works just fine for me. Fourth, I really don't notice the slow loading times.

But eh, it's your decision.
