- add some parts aimed towards a "download play" mode, which does not rely on launching from a flash card, but from different exploits. It does not work yet (you will get a "missing ini file" error message), but if I ever finish it, it should be possible to run using download play on a DSi/3DS. (Lacking the hardware to test it, it is unlikely it will be finished anytime soon, sorry.) - eliminate many warnings during the build process - modify auxspi.h/.cpp so that it no longer depends on global variables (I hope)
