- beta 12 (external booter changes).

- fixed launching of real nand channels.
- fixed launching of forwarder channels, but some apps (ie. wiimcc and savegame manager gx) don't connect with USB devices. if they are on real nand use the 'custom' option in game settings for these forwarders.
- fixed launching HBC on real nand. don't know if its even possible on a emu nand.
- 480p pixel patch for nand wiiware/vc games no longer requires apploader setting ON.
- Exclude Prince of Persia: The Forgotten Sands and a few games that use MetaFortress from using 480p pixel patch
- added giantpunes returnto patch for channels just in case not using d2x cios. some reason it was missing.
