Hey there I have 3.03oe-a and I can play hombrew game most of the time. I tryed to install to the new 3.71 mss or whatever but to start off with, I don't have a game150 folder. Mine is currenty just game. So what is the easiest way for me to get my psp to the newest firmware. And also why with some of my homebrew game (rg. The Simpsons Game) does it boot up and the show a loading memory card screen then turn black? Anyone know why?
