This document discusses the FM sound synthesis in the Commander X16 and in my x65 computer. Sound in Commander X16.

Sound in Commander X16 is generated by two sources that are mixed together: 1) by the Programmable Sound Generator (PSG) in VERA FPGA, and 2) by the MIDI FM-synthesis chip YM2151.

>ice40up5k-sg48, costs around 9.30 EUR/1pc

RP2040 is $1 and capable of emulating not only YM2151 but YM3812 (OPL2) _while_ playing full DOOM https://kilograham.github.io/rp2040-doom/sound.html

But it is not a FPGA.

Hardware is cooler, most of the time.
