Reprogrammable 4 Megabit SMS cartridge

For making dedicated cartridge versions of your homebrew games!

Description

This is a reprogrammable cartridge, perfect for easily making semi-permanent versions of your homebrew games! Built using our 4 Megabit SMS cartridge PCB. The sticker "4 Megabit Cartridge" is included but is not pre-installed, leaving you the choice to make and install your own.

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]
Tested and pre-programmed with the homebrew game DONKEY.SMS
(for demonstration purposes)

Does not contain battery-backed RAM, but with the right programming techniques, scores and progress can be saved directly on flash. The pre-programmed game, DONKEY.SMS, does that!

The cartridge shell we use were in fact designed for SD Card flash cartridges and have a small slot on the top which serves no purpose. If you'd rather use your own cartridge shells (from a donor game or otherwise) see also our cartridge PCBs.

^[1] We can develop a custom mapper if necessary for your game or project.
