I got a PSP phat from my friend for $50 tonight, and it had 3.03 OE-B on it already. I want to install 3.90 M33, and I know I need 3.52 M33 and 3.52-4 M33 first. The problem is, anything I put in the PSP/GAME150 folder isn't detected. If I put it in the PSP/GAME folder, it's detected, but it won't run. Any ideas on what the problem is? Nevermind! Apparently, having both GAME and GAME150 folders in existence makes them both visible. One can't work without the other. Now I feel so noobish lol.
