# soniccdrespinned: a cross-platform Sonic CD port built on the decompiled code

> soniccdrespinned is a cross-platform port of Sonic CD that runs the decompiled stage, special-stage, time-warp and title-screen code on a newly written platform layer. That layer decompresses the original SZDD-packed CMP sprite and tile bitmaps, streams ADX music from the US or Japanese AFS soundtrack, and renders through SDL 1.2 or SDL2, with PC and PSP input backends.
