Summary of the thread:
Problem 1:
The game is a 002b game. If ANY kind of main.dol 002 patch is applied to the game, it freezes at a green screen. You need cIOSrev13a to avoid this. If you get the 002 error then, it's obvious you need another loader/enable the 002 fix in your loader. Note that a green screen freeze could also indicate a region problem, try to play with disc region video mode, black&white playback means the game works and you only need to fix the video mode problem somehow.
Problem 2:
The game freezes for some people at the health screen. Mostly people using discs which are limited to 3x reading speed(softmods+flatcable modchips) report this. There are different solutions for this problem:
1. Play from sd or usb, works for most people
2. Press A,-,+ and/or home rapidly and/or with the correct timing, seems to not have too much effect
3: Press eject in the second the screen flashes white for the health screen, if you are promted to reinsert the disc, it worked. Confirmed to work by many people
4. Play without sd card insterted. 1 Confirmation so far
PS: Many people reported that some weird settings like force and patch video modes worked for them, but these were coincidences, patching a NTSC game to NTSC on a NTSC console is nonsense.
PPS: Oh yeah, why i do this: I can't stand the 100th post: "Hey guys, i found the solution, press eject in the right...."
