Here is my CBM emulator running on an M5Stack CoreS3 with watchband, UART cable to Adafruit ItsyBitsy (like Arduino Leonardo) to C128D external keyboard.
Both C64 and C128 cores are included. Text, SD/D64, 6502 emulation support included. No it won't run your graphics/sounds/games, but will run simpler programs. Open source!
