The only major changes to the source code were removing functions related to launching system executables and getting the system's time. Other small changes were made to the file manipulation functions- they try to initialize FAT before use but it is recommended you do this yourself! The makefile might need some configuration to reflect your development environment.
alternate download ==
Feesh's server seems down at the moment, a mirror can downloaded from [http://www.box.com/s/n5dmlncn0dicbsx4b16i here] (its not exactly a mirror copy but it should work)
If you'd just like the development files they can be found [http://www.2shared.com/file/-2meQZx6/lua-wii.html here].
