This is an open source project that aims to create a MSX cartridge that acts as a old disk drive interface but in fact it will be accesing a modern SD Card. For the MSX it will be as if there is a magnetic disk drive with a real magnetic disk but for real it will be accessing a .dsk file inside a sdcard.

Development tools used are:
- Kicad version 2013-07-07
- Microchip XC8 v1.21 (free mode)
- Micrchip MPLAB X IDE v1.90
- Altera´s Quartus Web Edition 11.0

  • It combines the disk interface and a conceptual disk unit in one package. So with just one cartridge and one sdcard you are good to go with your games and apps for msx.
  • It abstracts the old disk interface in a much more effcient manner meaning that disk access is faster with this interface.
