Many Neo-Geo games have debug menus and development tools lurking in their code, waiting to be discovered. Some are as easy as messing with the Debug DIPs, while others require more work.
Twinkle Star Sprites
If ROM address 0x0000FF (0x1000FE in an un-byteswapped "224-p1.p1") is set to 0xDB, debugging features will be available.
Program Menu
The main debug menu, "--- PROGRAM MENU ---", is accessed by holding down Player 2's A, B, C, and D buttons on boot.
Select Button Menu
Another debug menu is available by pressing Player 1 Select at any time.
The Last Blade
The Last Blade has a tool menu; more research is needed. (This was discovered on 2ch.)
In "234-p1.bin" (un-byteswapped?) make these changes:
- 0x5F5F4: 0xAA → 0x40
- 0x5F5F5: 0xF3 → 0xAF
