Yeah, unfortunately, the game was never dubugged well at the Japanese company and features some pretty terrible examples of programming. There was a reason so many bugs had to remain unfixed in our patch. We tried to fix them all but due to some awful programming it just wasn't feasible. There is even a dummy treasure chest in the final castle that can't be opened even if you cheat and can get to it. Forgot that one in the readme
I've seen some buggier games, but this one is up there. At least it doesn't lock up during a major boss battle like Ar Tonelico 2 does
And even with the bugs, the story was so much fun, I can look past them personally. These little funny comedy style RPG's are some of my favorites.
There is a cheat to keep the money code from locking up, but it isn't published out there much.
Make sure you add 7E13BC 00 (to stop it locking up). The game tries to put a 01 where it shouldn't if you don't do that. They didn't take into account it shouldn't spill over if you max out money.
