Button actions for gba mode and filebrowser changed:
- GBA mode trigger now occurs on B button instead of A button as some flashcarts like DSTT use a launcher that already uses this button for GBA mode.
- FileBrowser trigger remapped to trigger from any button not assigned to the other actions. So if shoulder buttons or Start/Select button is used file browser comes up. This ensures user can enter filebrowser without triggering any special mode their flashcart's main loader might have for the button they wanted to use. This isn't relevent for original R4 but if user wishes to use this bootstrap on other carts (like DSTT) then it would have been an issue. DSTT apparently boots into GBA mode if B was used on boot.
Use r4bootstrap.nds if you wish to use this on something other then an original R4/og R4 clone. gbaframe.bmp provided as an example frame for GBA mode. Matches the DS Firmware theme for the GUI setup for this verison of Hbmenu/bootstrap.
