Progress is being made on the Atari Jaguar SD cartridge. It’s now at the basic fail-safe state of booting code from the on-board FLASH chip. This will contain the menu / game selector code to allow you to load and run games from the on-board 16MB RAM.

Next up is starting work on the big CPLD which controls the RAM access. Once the RAM is functioning I’ll move onto the microcontroller which will handle the SD card access and other tasks.
