I'm curious if anyone here has done any testing of game performance when you play roms off the SD Card versus straight from a cartridge? Would I possible get better controller responsivity if I use carts? I don't have any yet, I've only tried roms. Every now and then even when using an original wired Nintendo controller, I get the occasional input dropout if I press the button super fast (for instance in Ninja Gaiden if I jump and then start pressing the sword swing button rapidly sometimes it won't even swing once). The problem seems to happen more often when I use the 8bitdo controller. Or is it just my controller? I've already been to the local retro store and tried and returned a few. The problem seems the same...
