i got a UMD movie today that requires 2.6 fw to play. as of right now, i have a 1.5 fw psp which i am planning to mod with custom firmware 3.52 m33, and therefore, i am not going to touch the upgrader that came with the movie itself. i am aware that i cannot play any umd games with this custom firmware but i wasnt sure about the purchased umd movies. please let me know if i can play this movie that requires 2.6 fw with a custom firmware such as 3.52 m33. thanks.
