EMULATORS: If emulators such as no$gba, it's because by default, the BIOS firmware language isn't set as English. If multilanguage etc., it automatically sets the language accordingly to your firmware language. Try this method. Get any GBA ROM. And then change your settings so you load the BIOS (GBA BIOS in settings), and then saved settings and reset. And then while you're in the DS firmware, go to settings and change the language to English. Save the DS settings, change back to load cartridge directly and then save no$gba's settings. And then load the game. Should work.
