On Romhack Thursdays, we bring you interesting finds from the world of game modifications.
Early Sega Master System units released in the US had a small game included on the system ROM. It’s not as cool as the Space Harrier music with FM synthesis included on some Japanese Mark III units, but it’s at least a playable game.

It’s not really that deep a game, just a simple timed maze race, but it’s something, in case you got tired of Hang-On and Astro Warrior. Mike (no last name given), the maintainer of the blog Leaded Solder, decided to take that game and make a cartridge for it, so it can be played on any Master System, not just the early units that had it built-in. It’s a story of electronics work and 3D printing, of ColecoVision cartridge simultarity, roadblocks overcome, and ultimate victory. Here’s some appropriate music to listen to while reading it.
