I've wrote a post about API/driver interface I've designed and implemented for making various devices equipped with OPL soundchip (responsible for that AdLib / SoundBlaster specific sound in old PC games) talk with SCUMMVM on Atari Falcon 030 (,but not only) and little bit about development itself. Some of it was already posted on Atari Forum / YT. https://nokturnal.pl/2025/07/nokturnfm-goes-scummvm #atari #scummvm #atarifalcon030 #atarifalcon #ct60 #retrocomputing #software_development #nokturnfm2 #nokturnfm3 #opl3 #opl2

#nokturnfm2 #nokturnfm3 #opl2 #opl3 #atarist i've assembled new pcbs and put them into shells for a first time. I've misplaced reset button hole in opl3 version of course, will fix it in next iteration. Several screws are too long in fm3 version, need to trim them down few millimeters, but it's not visible..

#nokturnfm2 #nokturnfm3 #opl2 #opl3 #atarist i've finished cartridge shells. And i've made some tests with pcbs and screws to see if everything fits. I will probably add either label and/or bezel cart name on top, maybe some minor tweaks will be needed. So, now i need to solder new pcb versions and assemble the whole thing.. 😛

#atarist #nokturnfm3 #opl3 #ym262-m So yeah, i call it first draft of a shell for my opl3 fm cartridge. Dimensions are right, hole placement ok, filament poles weren't good enough and broke really quickly, so i will need to use proper screws instead. Still #nokturnfm2 version to finish.. Made in #freecad on which i don't have full control yet ;)...
