LSDJ provide a sync feature, similar to sync24 (24ppqn, or “pulses per quarter note”),, with the difference that the gameboy do not wait for pulses, but bytes (so 24 bytes per quarter notes)

So converting Sync 24 to Lsdj is quite simple : Every Sync 24 pulses must be changed into bytes (0xff, or b11111111)



Check this gwEm page to learn how to generate “bytes” with a NE555 :

Thanks to gwEm and Johan for details.
