After 10 years, the high score system for DCSquares has finally stopped working. Rather than update it to be compatible with PHP 5.x, I'm releasing the source to the original Dreamcast, Windows, Mac, Linux, and iOS versions, as well as unfinished ports to Android and OUYA. The original versions of the game depend on libraries that haven't existed in a very long time, and the Mac binary is PowerPC-only! Everything is available on Github: https://github.com/c99koder/DCSquares
