Classic 10×10 battleship for the original Game Boy: a seven-ship fleet that never touches, and three AI levels up to a HARD mode that maps your ships.
Classic 10×10 battleship with a fleet of 5, 4, 3, 2, 2, 1, 1 — and ships never touch. Take a random fleet or lay out your own on the boot menu. The computer plays at three levels, chosen with SELECT: EASY fires at random, NORMAL hunts with neighbour targeting and line following, and HARD keeps a probability map of where your ships can still be. Hit flashes, last-shot markers, noise-channel sound and a game-over breakdown of shots, hits and accuracy.
English draughts (checkers) for the original Game Boy — standard rules, compulsory captures and multi-jump chains, against a built-in machine opponent.

A homebrew pseudo-3D racer for the original Game Boy: three tracks, two rivals plus traffic, hills, bends you can see coming, and 27 lap records saved to the cart.
A lunar lander for the original Game Boy: bring the ship down on a pad, in one piece, without much fuel to spare. Gravity is always pulling, the engine is the only thing that beats it, and fuel is the whole clock.
Asteroids, on a screen that wraps at all four edges. Turn, burn and fire, and keep breaking the rocks down until there is nothing left to hit you
Three tracks, two rivals, traffic, hills and a road that bends towards the horizon, on a Game Boy with no 3D hardware at all. GB Racer is a proper arcade racer in a 128 KB cart.
Four random maze floors, three kinds of monster and a gun, rendered in true first person on a 1989 Game Boy. FPS Dungeon shouldn't work. It does.
We kept rebuilding the same Super Game Boy border kit for every game, so we fixed its bugs, added real tests and gave it away. Here's what's in GB-SGB-Tooling.
