My brother has been trying to play chrono cross on his psp with 6.20 PRO-B10 but it freezes in a battle. I was told he needs to set up popsloader 6.XX and use 3.7, i've installed popsloader and enabled it in plugins in the recovery menu but when i start the game with the right shoulder button held in the poploader menu don't come up. Anyone tell me why this is happening.
