TangNano 20K cartridge for MSX computers
https://github.com/lfantoniosi/new-juice
This cartridge allows any MSX computer to host a Sipeed Tang Nano 20K. The current fpga core implements:
- MicroSD Nextor 2.1 Drive - FM OPLL + MSX Music ROM - 2MB Super Mega RAM SCC+ - 4MB Memory Mapper - Sega Master System VDP + PSG to allow running SMS roms from SofaRun (Franky HDMI)
The Super Mega RAM SCC+ is a different ACVS-like MegaRam that support different mappers:
