Return of Samus: Unused Code Segments

Bank 0 is filled nearly to the brim with code, leaving little room for custom assembly code. However, there are pieces of code that never get touched at all, and can be overwritten or zeroed out without impact on the game. This page aims to list these unused sections of code.

Location Description
0x0393-0x039A Unused code that copies 0xFF terminated data.
0x22E1-0x235B Unused tile-related code.
0x2FC8-0x2FE0 Unused death sequence call.
0x3062-0x30BA Unused death sequence.
0x3B43-0x3BB3 Unused game modes.
0x3F07-0x3F5F Copy of unused death sequence.
0x3F60-0x3FFF Free space. Used in EJRTQ though.
