And to really sell the effect, I decided to add some color grading & lighting effects to react the same way for the background. I might do some more tracks with this.

The original track used is by @bryantobikomi.bsky.social!

25. Dungeons of Aether - Smoldering Blade
I haven't played this but what a killer FM track this is, it just nails that texture and feel of the OPN2/C chipsets and then some. The bailout of the 2nd verse at ~1:04 is SO PRETTY too, the backing chord progression + that little main line lilt is SO good.

(I defy anyone to tell me a better 16bit sound chip than the Yamaha OPN2. You can't. You just friggin' can't.

Go on. I'll wait. That's the one that was in the Sega Mega Drive/Genesis. It also had Low Volume Distortion. Come the fuck on, it walked so Korg synths in the early 2000s could run)

Konami's OPN2 operator blocks are similar to GEMS's, except with SMPS 68k's operator ordering of OP1-OP2-OP3-OP4. SMPS Z80 and GEMS share the similar operator ordering of OP1-OP3-OP2-OP4.

Konami OPN2 and GEMS operator blocks share the same parameter order of:
DT/MUL->TL->RS/AR->AM/D1R->D2R, SL/RR

Hm, looking at pulling in Nuked OPN2 into my fantasy console since it's one of very few off the shelf YM2612 emulation libraries I can even find, but it's LGPL.

Trying to figure out options to comply with that license...

Working on a SID chip emulator, inspired by Nuked-OPN2
ym3438... just for fun, this is something I wanted to do since... ever. It occurred to me that probably already exists something similar out there. :P

Well, let's ear how it works in my game engine...

thanks
my mention is more for the hardware echo implementation on those kalimba parts, what really gives it that extra edge, like it's being played in a spacious, empty room
it's pretty integral to how good it sounds so I was trying to see what opn2 ssg-eg could replicate

YM2612 (OPN2) は、1988年にヤマハが開発した4オペレータ、同時発音数6音ステレオのFM音源機能を持ったFM音源チップです。

FM音源部についてはYM2608 (OPNA) と同等の性能であり、特有の厚みのあるサウンドを出力可能です。尚、ADPCM等は搭載されていませんが、FM音源部のチャンネル6を使って8bitリニアPCMの再生が可能になっています。

このチップはメガドライブやFM-TOWNSなどに採用されました。

尚、メガドライブの後期型等にはCMOS版(凄く簡略化して言うと、低消費電力型)であるYM3438が搭載されています。性能は、基本的にはYM2612と同等です。

MELさん、改定前の投稿に続き、こちらにもご返信ありがとうございます😊✨

ご存じの通り、日本とは異なり海外の一部地域(南米など)で爆発的に普及した海外版「Master system」にはOPLLが初めから載っていませんので、コストは確かに大きかったのだろうと思います。

ま、セガは後に出したメガドライブ/GENESISに当時非常に高価だった16bitCPU「68000」や、4オペレータのFM音源「OPN2」を搭載していますので、それよりは痛くはなかったかもですね😅💦

あと、パチスロ台に関しては完全に「チップが安価だったから」採用した、ってだけなんでしょうね・・・。

I had a mate wot had a GeneDrive, I mean, the YM/OPN2 was rarely used to its full extent, and it certainly sounded more chippy than an Amiga, which was supposedly "better" at the time, but these days- Well, this says more than I could: youtu.be/gWVmPtr9O0g
