In the Game Boy Advance System ROM, a sound program is included and is responsible for
things like startup sound. By using a portion of the sound program with this system, the programs in
Game Pak ROM and Internal RAM can be minimized. However, the following restrictions and differences exist: -Slower speed than Internal RAM execution version (sys_rom = 0) -Cannot limit the processing time of m4aSoundMain( ) -Must use 2 channels for DMA -Operates only with Development AGB (TS4) and later. If you want to use the sound code in the System ROM, tell the sound engineer to "Add sys_rom = 1 to the definition file mks4agb.ini." |
