TEST MODE


A debug menu called TEST MODE begins at SNES address. There is no in the programming to reach it, however. A string of nine bytes located at SNES address  possibly contained the original entry point at one time.

Use these game enhancer codes to access it:

Game Genie 44BD-A40D DDBD-A46D 6DBD-A4AD DFBD-A7DD

Pro Action Replay 00930922 00930A00 00930B80 00930C01

Activate the codes at bootup, and wait for the intro logos to pass without pressing any buttons.
