CorsixTH aims to re-implement the game engine of Theme Hospital, and be able to load the original game data files. This means that you will need a purchased copy of Theme Hospital, or a copy of the demo, in order to use CorsixTH. After most of the original engine has been reimplemented in open source code, the project will serve as a base from which extensions and improvements to the original game can be made.

CorsixTH uses SDL and LUA, both of which are included in the source archive ready to be built for the wii. Note that SDL has been modified specifically for CorsixTH.

Changes:

– Many fixes from Corsix-TH SVN. Including (but not limited to) no more stuck patients or handymen, variable speed doctors, doctor promotions, patients sometimes vomit/litter/wet themselves…
– Rewrote the input handling to make proper use of all available SDL joysticks (including gamecube controllers)
– Reworked the video renderer slightly.
– Rewrote the audio renderer to use libaesnd; channels are no longer reversed.
– Newest libogc (no more random crashes when using a real mouse).
