asq is a simple frontend for MAME/emulator cabinets. It runs in a terminal window using curses, and pops up an optional screenshot window. It uses MAME/emulator keybindings so you can control your MAME cabinet using just your MAME controls. (In fact, this is where the name comes from--player 2 buttons 1, 2, and 3 are "asq".) It can also remap your games to use MAME keys. asq is meant for people who don't want to use a keyboard and have lots of games to manage.
Mutant Storm is inspired by RoboTron, Smash TV and Jeff Minter's Llamatron. It has separate move and shoot controls, allowing the player to run away and still fire back at the pursuing hordes. Set in over 89 levels of psychedelic 3D environments, getting ever more crowded with nasty beasties, all generated in a state of the art game engine, Mutant Storm is for gamers who want pure action.
Trackballs is a simple game similar to the classic game Marble Madness. By steering a marble through a track filled with vicious hammers, pools of acid, and other obstacles the player collects points. When the ball reaches the destination, the player continue to the next, more difficult track - unless, of course, time runs out first.
