v5.1
- Changed the payload chainloader to load payloads named "BUTTON_NAME.bin". As an example: "up_Decrypt9.bin". "default.bin" was changed to "def_NAME.bin" ("NAME" can also be omitted). Original idea and code are by @habbbe, so thanks!
- Fixed bug when exiting AGB_FIRM and not having an updated SysNAND, where the last used FIRM would be remembered incorrectly, thus loading 9.0 FIRM and forcing the user to reboot to play a GBA game again.
