So I have an r4 card that I use to play all my DS backups and the compatibility is really good (except Pokémon Platinums bag menu lags a little bit for some reason). That being said why is it that you can’t simply play DS backups from the 3DS SD card with the same 100% compatibility as when it’s being read from the cartridge slot? I know they allow you to play DS games from SD now but I read it’s still not as good as a flashcart?
