Yeah that would be my recommendation too actually! How'd I forget.Nesds is my favorite homebrew for emulating. I would recommend using the ultimate injectors for nes games
Being serious... 3DNES is awful (I converted it to a CIA file so I can run it on CFW). It lags really badly in the menus to the point where I can't even get to my ROMs... QuickNES works really well though. I've never noticed any issues...BRUH! NESDS from the nds-hb-menu or TWLoader. Works on all systems
P.S. I'm joking, it's a ds emulator. Still works tho...
