My standalone Arduino-based Famicom cart dumper is complete. Reads all Licensed mappers and one Unlicensed mapper for a total of 66. Reads and writes all SRAM and EEPROM saves from Licensed carts. NES carts are read using a NES-FC adapter.I'm waiting on two additional test carts and my NES-FC adapter PCBs before sending the hardware and sketch to sanni. I'm also debating whether to attempt to add some type of mapper detection code as the reader currently requires manual selection of mapper, PRG size, CHR size, and RAM size. I have constrained the PRG/CHR/RAM sizes based on the mapper so that makes it somewhat easier.Whether my FC/NES stuff can be merged into the main project will be up to sanni as I'm not sure what will fit into the hardware and software.
