Mother 1+2

Mother 1+2
Developer: Pax Softnica Publisher: Nintendo Platform: Game Boy Advance Released in JP: June 20, 2003 This game has unused graphics. This game has unused music. This game has debugging material.

Mother 1+2 is a port of Mother and Mother 2 to the Game Boy Advance. While 2 got a few bug fixes (as well as inferior audio, which is inevitable with any SNES-to-GBA port), 1 had a whole slew of improvements, many of which came from its then-unreleased English version.

To do: Since the two games seem to be near-direct ports of their console counterparts, some of their other unused content could be lurking around as well. There's other unused jingles. Document the debug menu.

Unused Graphics

To do: Assemble these and post comparison with used graphics.

0x6F57B4 contains a version of the game selection screen with English text for the prompts.

Unused Music

Mother 2

The remixed Mother cave theme is still present and still unused.

Mother 2 Debug Mode

The easiest way to access the debug menu is by changing the data at ROM offset 0x1F0-0x1F3 from A5 37 01 08 to 55 7A 00 08. Doing this will auto-boot the game to the debug menu.
