Debug Leftovers

The BANK6 of every regional version of this game contains the debug code in as much as about 1/4 of its data, as well as text for it. While most or all of the related programming is still present, most of the JMP and JSR instructions no longer point to valid addresses in any version of the ROM, meaning the functionality was scrapped at some point before release. Even worse, the beginning of this bank should contain some portions of code used by some debug routines, but that has been almost completely replaced with a copy of the DPCM data from the last banks in the beginning and copy of BANKD data at the end of ROM. Judging from the data, they might have intentionally damaged this debug code on purpose to prevent players from seeing any of the debug material.
