The svn repository for the code is now available at :

http://code.google.com/p/wagic

For the moment, you can only checkout a read-only version of the code. If you want to add changes to the game, send me directly your code. We’ll consider opening the project for writing to people who send us lots of useful code 😉

You need to copy the Res folder of the PSP version to the Res folder of the sources for the game to run correctly
