Finally did some haxchi work again today, now its using devkitppc r28 which makes for smaller files and I've added support for 6 new games, adding up to 16 games by now!

One thing I would like to mention, it is entirely possible that zelda spirit tracks is already compatible with this, somebody has to test that though by uploading the super mario 64 ds zip file into their game and tell me if it works, if it actually does then that brings us up to 17 games total.
edit: spirit tracks now is also part of the v1.8 release, so now it actually does support 17 games.
