A quick port of VBA-next(VBA-M https://github.com/libretro/vba-next ). I developed it on 4.1 so, it definitely works on this version. It's partly based of 3DSGBA https://github.com/shinyquagsire23/3DSGBA Works now perfectly for meFor more infos see here: https://github.com/RSDuck/vba-next-switch Get it here: https://github.com/RSDuck/vba-next-switch/releases
