jayred and nanoage: that's not the point. The point is to be able to select a dash to boot up that is outside the scope of the bios looking for a dash to boot (looks for evoxdash.xbe first, then neXgen.xbe, and finally xboxdash.xbe). Avalaunch and MXM aren't even looked at unless you change the name of the xbe file to one of those three. This app will load first and check to see what dash you want loaded.
BTW, will you be able to select which 8 are the 8 selectable (in the hypothetical situation that several more dashes are released eventually)? Also, what would the name of the xbe be? Would it conflict with the ability to load the M$ dash (with the modchip disabled) to use XBL?
