So I'm getting ever so closer to getting something to run on my gb emulator, but it still doesn't play anything, it'll run, but eventually just get caught in an infinite loop or it'll halt itself. Now, I have no clue where the problem is becuase it executes several hundred opcodes before it ever crashed, which does a decent job at obfuscating the problem, so I'm thinking of comparing the program flow to another working emulator, so I can see where it starts to come adrift, are there any GB emulators that let you see (or can easily be modified to let you see) the value of the program counter, key values in the ram, currently executing opcode, etc? I tried VBA but couldn't figure out a way to do it, but apparently others were able to so
