TetriCycle is Tetris projected onto a cylindrical surface. Rotate the cylinder left/right such that the descending piece falls into place. TetriCycle is freeware, can be distributed freely and should never be charged for.

Changes:

Shadow option — see where the current piece will drop.
Preview option — see what the next piece will be.
Multiplayer looks better. Each playfield is drawn from the same perspective, but with a shifted viewport.

Castles of Dr. Creep is a 1984 Commodore 64 game written by Ed Hobbs and published by Broderbund Software.

This project is an open source rewrite, allowing you to play the game using an image (D64) of the original disk.

Presently it can compile and play on both Windows, Nintendo Wii, and Linux (Ubuntu specifically has been tested).

http://creep.sourceforge.net/

Downloads codes from the WiiRD Code Database (http://geckocodes.org/) to the SD Card then allows you to select the codes you want to use. Finally, it creates a gct file that Gecko OS or Gecko OS Mod can apply to the game.
