* Can now use gbaframes specific to a gba rom being loaded to ram/flash. Have a bmp file with filename matching the game rom being flashed in GBA_SIGN path. If it finds a matching BMP it will use that before falling back to the default gbaframe.bmp paths. * nds-bootstrap now used for booting retail NDS roms from file browser. Note that currently GBA-Exploader does not create new save files so only games with existing save files (currently hardcoded to GBA_SAV path like with GBA games) can be booted with this.
