I’m a southpaw. It mostly goes unnoticed these days but when I was younger I used to get annoyed at the right-handedness of the world. I was truly awful with scissors and would constantly be told off for leaving things the wrong way round! I never really considered the impact on me when gaming, but perhaps I should have! This Goofy Foot NES controller PCB essentially allows you to create a perfectly left-handed NES controller. When the controller is upside down, the D-Pad and buttons are re-mapped to work correctly.
Apparently, this isn’t only desirable for the true left-handed retro gamer. It’s a technique used competitively by professional and amateur Tetris players who prefer the D-Pad to be in the right hand. Digging deeper into the product description from EricIcx they actually offer a range of modifications so you can get the NES controller you require. They offer modifications to vintage controllers and modern aftermarket clones. They are also replacing the rubber button membranes and modifying them to give the best and fastest response. They also offer a range of different key bindings with suggestions as to why they might be beneficial for different player styles and games.
There’s such a level of detail in the product description; you can tell by reading it that EricIcx is really dedicated to getting the best out of this classic controller design which is heartwarming to see!
