frntc/SIDKick: SIDKick -- the first complete SID 6581/8580-drop-in-replacement that you can build yourself

SIDKick is a versatile sound device for C64s and C128s: it serves as a drop-in replacement for the SID 6581/8580 sound chips, and at the same time provides Sound Expander-emulation (Yamaha OPL-based FM sound), a MIDI interface and can control LED stripes. It is based on a Teensy 4.1 and makes no compromises with regard to quality: the emulation is based on reSID and fmOPL. It also comes with a few extras.
