Ok so I have a hacked psp using 5.03 Gen-C. I really want to get cheats for this one game because I'm having a lot of difficulty on it. So at first I tried using Cw cheats all the installation stuff was in check and everything was enables but when I went to the game and tried to open up the cheat menu, it never showed up. I tried everything!! I checked it, re downloaded it, and everything. But nothing seemed to make it pop up when I play the game. So I tried to use a different cheat device, I tried using Cheat Master Fusion, I enabled it on the psp and when I played the game the exact same thing happened! I was unable to make the cheat menu come up. I'm not allowed to upgrade my firmware cause if I do one of the games that my brother plays won't be able to work. I need help on figuring out why none of the cheat menus pop up.
