Reprogrammable 4 Megabit SMS cartridge circuit

For making dedicated cartridge versions of your homebrew games!

Description

This reprogrammable SMS cartridge circuit, perfect for easily making physical versions of your homebrew games! Can be installed in standard SMS cartridge shells.

Specifications:

Re-writeable 4Megabit (512 kB) flash chip
Compatible with PAL and NTSC systems
Compatible with the power base converter (or equivalents)
Sega-style mapper (slots 0, 1 and 2)^[1]
Fits in standard SMS cartridge shells
Tested and pre-programmed with the homebrew game DONKEY.SMS
(for demonstration purposes)

This design has no battery-backed RAM on-board, but with the right programming techniques, scores and progress can be saved directly on flash. The pre-programmed game, DONKEY.SMS, does that!

If you do not have an empty cartridge shell to fit this PCB, see also our reprogrammable cartridge.
