So I got a bug to play Chrono Cross recently on my hacked PSP (running 6.20 Pro-B for custom firmware). Unfortunately, it seems this game has all kinds of woes with actually getting it to work. First eboot I found wouldn't get past the Square logo. Then the second. Then I finally found one that did, but it would immediately lock up upon killing the King Moaman boss on Guile's route into Viper Manor. Looking it up, this seems to be a common problem

So I started over (had no choice, since I didn't have a save that would let me try another route besides Guile's). This time, the game locks upon killing the Mama Komodo boss in the very beginning. Again, seemingly a common problem, but one I have no idea how to get around. Anyone else have this issue? Any way around it?
