Notes

External SFX

The drivers support dynamically "releasing" channels, which can then be used with any SFX and/or sample playback engine.

GBSS and DevSound X samples

GBSoundSystem and DevSound X internally support playing back 1920 Hz samples. If a higher sample rate is needed, they additionally support external sample engines.

GBSS + RGBDS

Game Boy Tracker generates output designed for an older version of RGBDS; it must be modified a bit, including by changing the DATA section type to ROMX.

DGB + RGBDS

Please refer to this page.

GBT + GBDK

The GBDK port of GBT Player stopped being maintained long before the RGBDS version, and therefore lags behind.
