1/2 @Judeau @stefanjl Because it is quite fresh. Well, adoption is quite poor to be honest in comparison to let's say c64 or Atari 8-bit (I don't have any influence on people), but I've open sourced library (C99, https://framagit.org/nokturnal/nfm), I've made docs about usage, which eases adding opl support along with player (it needs some more work as always). #atarist #opl3 #opl2

:atari: Last week I've finished batch of NokturnFM2 and NokturnFM3 sound cartridges. Will start to pack them next week and move on to handle international preorders. After sending parcels I will be able to focus more on software side. I've donated four of them to next week's SV2025 WE Atari demo party (https://sillyventure.eu) in Gdansk,Poland, so anyone participating in Atari 16/32 bit competitions will have a chance to win one. #atarist #atarifalcon030 #opl2 #opl3 #ymf262 #YM3812

NokturnFM cartridges preorder has ended, thank you for everyone who preordered one. Now I'm entering preproduction phase figuring out updated production costs, so stay tuned... #atarist #opl3 #opl2 #nokturnFM

NokturnFM cartridges (sound expansion) preorders end in a week (10.10.2025).. #atarist #YM3812 #YM262-M #opl2 #opl3 If you want to get one, it's time! https://nokturnal.pl/posts/nokturnfm_preorders_one_week_left. Unfortunately due to US tarrifs by mr. Orange sending anything to US and Canada is not possible (still you can register interest, but sending parcel will be suspended until situation clears out)...

I would like to inform that I've started collecting preorders for NokturnFM2 / NokturnFM3 cartridges. NokturnFM2 and NokturnFM3 are Atari ST (and compatible) sound cartridges equipped with OPL2 (YM3812) and OPL3 (YMF262-M) soundchips enabling FM sound synthesis capabilities with minimal cpu overhead. More details can be found find in official announcement (https://nokturnal.pl/posts/nokturnfm_preorders). #atarist #opl2 #opl3 #NokturnFM #YM3812 #YMF262-M

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

Spend several days on hooking up and testing my OPL2/3 backend (FMlib) and integrated it with SCUMMVM to allow AdLib emulation via real Yamaha OPL soundchips (like those found in my NokturnFM cartridges) on 16/32 bit Atari's. I've recorded some footage directly from hardware (unfortunately video is a garbage from composite output, couldn't grab it the other way ;(, but on RGB monitor it looks awesome). #atarifalcon030 #OPL2 #scummvm #ct60 #NokturnFM #atari

#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.. 😛

This is a Yamaha OPL2. Sanded down and relabeled with a bogus datecode! Why do they do this...? So annoying. It works, but the original markings would have been much more useful.

The OPL Archive - Release 10 is live!
This nice little update adds 69 songs, including the EMS Music System, covers by unknown authors of the Korean AdLib scene, and the oldest OPL2 songs yet - the demos from the Yamaha PSR-11 keyboard (1986).

looking for tips on how to give #opl3 #opl2 #adlib #ymf262 kick drums more utility. I can also dedicate a channel to kick rather than the kit so it may be played chromatically, primarily, how could I get a downward sweep in pitch w/ this basic fm synthesis?

#atarist #opl2 #opl3 #nokturnfm I've published official webpage containing info related to NokturnFM2 / 3 cartridges, which allow use of Yamaha OPL2 / 3 soundchips with Atari ST and up. Right now is rather short project description, some programming info and NokturnFM.play, which allows music replay with various devices. Not everything is there yet, lot's of work, not much time, so stay tuned. https://nokturnal.pl/home/atari/nokturnfm
