tueidj directed " Corsix-TH ", a port on the Wii most excellent game management in a hospital on the same PC name.
For those who haven't heard of it: Corsix-TH is an open source reimplementation of Theme Hospital, using Lua and SDL. It requires the assets from the original game (the demo version is included in the above package) and isn't quite complete, there's a few diseases and scenarios missing. It's definitely playable, although this build has audio disabled until I can free up about 20MB of memory somewhere.
Just dump the files onto your SD card as is (the CorsixTH dir must be in the root).
