Flash cartridge

Copy games to a microSD card, pick one from a menu on the console, and play. Saves are kept for you.

The cartridge loads the chosen game into its own memory, then the console runs it as if it were the original cart. Battery-backed memory holds your save between sessions, and the menu copies saves to the card at the next boot.

The gateware, menu, and firmware are our own. It’s meant to run homebrew written for NileSwan as well.

IR, sonar, and other special cartridge accessories aren’t part of the first version.
