View Full Version : Luigi's Mansion Possible Diagnosis

When I ran Luigi's Mansion in the 1.03 beta, it got to the point at which it usually crashes when a dialog box appeared that said that the command "twi" wasn't implemented. Could that be the cause of the problem in Luigi's Mansion, and possibly other games?

Just was wondering if anyone knew about that, or has any knowledge of whether it's gonna be implemented.

Did you know about this already? Can something be done about it?

Pay attention. As stated by this quote by fires,


Luigi jumps to zero and executes undefined code

It seems that the game is executing undefined code.
It is not as unimplemted opcode, but something else is causing the emulator to jump to a faulty address within the executable code.
