I don't know what the heck is going on here. I was already aware that NO$GBA doesn't like Wan Wan Meitantei for some reason: the game likes to freeze at inopportune times, something it doesn't do in VisualBoy Advance.
But now I'm discovering that my latest batch of hacks are causing the game to freeze or glitch in NO$GBA (while, of course, VBA runs the game with no issue) in other places. So, does anybody have any clue what's happening? I don't want to think that the debugger I paid fifteen bucks for is suffering from inaccuracy problems, but unless WWM is somehow so shoddily-made that a "proper" emulator rejects it, it seems like the only possible conclusion...
