Atari ST OPL2/OPL3 carts (prototype)

Recommended Posts

Posted (edited)


I've finished prototypes of two Atari ST cartridges equipped with OPL2 and OPL3 chips (you know them if you heard Sound Blasters).

Both prototypes started to work yesterday. I've tested both on plain ST and results were quite good enough for a prototype.

OPL2 is too noisy for my taste.


I'm attaching sample output from both carts recorded from cart plugged to 520ST+.

FM Melody Maker(OPLL) cart support in players

Additionally I've wrote drivers and vgm replay for OPLL cart FM Melody Maker(made by Hybrid Arts in '89), which contains variant of FM2413B chip (,which is crippled OPL2 chip with predefined instrument set, 😞 used in MSX/MSX2 computers for instance)

FM Melody Maker cart tune MSX. Cart wasn't usable before without software package supplied with cart.

I've recorded several video/audio captures of 520ST+ equipped with my two OPL2 and OPL3 cart prototypes and replayed standard OPL3/OPL2 tune playlists which I've used on other devices.
