I think peripherals like this are cool but you probably are better off just plugging a USB keyboard into your console. The Wii was a shit console IMO but monster hunter tri let you plug a computer keyboard into the back of it and type which was a real quality of life game changer if you played online with people.
I’ve honestly never liked the ps2 controller though- on paper this is nothing wrong with it but when you hold it- it’s too small and cramped. I always felt like it needed to be like 5 or 10 percent upscaled. Both Xbox controllers were great. The GameCube controller never felt like it was too small or anything. The ps2 controller always felt like it was made for really tiny people with small hands. I think part of it is that made it too flat. There just isn’t much to hold and for a lot of adults the handles are just too small. Slapping that thing on it would probably make it worse.
