Here is MegaZeux, the game creation engine and runtime.
The port itself was done by exophase some time ago, I've just grabbed latest version and package it with a couple of cool games.

There is 2 software here: The Runtime, just to run games (found in "Action" submenu). Here, I use the Notaz SDL, and the Megazeux editor, where you can run or create/edit games. It's fullscreen by default but I don't use Notas's SDL here, so you can switch to window mode (with Ctrl-Alt-Enter), if you need to use other things while editing a game (also, the tools like png2smzx are shipped, access them in another teminal and go to /mnt/utmp/megazeux).

The "action keys" of Megazeux (Z, X, C and V) are also mapped to Pandora Buttons {A}/{B}/{X}/{Y}.

The games included are Pandora's Gate, from Lancer-X, an awsome RPG (mouse driven) coded for 24Hrs compo, and Ruin Diver III, from KKairos, a difficult (Dpad+Button) action game.

Go to http://vault.digitalmzx.net for more game (you should try Red from Lancer-X also) and info about this Game Engine.
The games should be unzipped inside appdata/megazeux/games
