* Stage2 launcher UI added. This is a heavily modified HBMenu with ability to launch carts! This menu can be used to boot a bootloader NDS file for flascharts that the direct cart launcher fails to boot. * New audio files added for new menu. * HBMenu UI loaded by default if booted with no cart inserted. * INI file folder now located in NTR_Launcher folder instead. A default ini file from NitroFS (if mount of nitrofs succeeds) will be copied to SD if one is not present. * Stage2 launchers are expected to be in NTR Launcehr folder though you can navigate to any folder you want in the UI so stage2 launchers aren't the only thing this can be used for. You can also use this as a means of booting homebrew off SD in NTR mode.
