I also purchased one of these, and I’m very familiar with the original Hori pad, I borrowed one from my friend and gave it a ton of use. I am very discerning when it comes to plastic feel, button feel, responsiveness etc, and this controller falls within 1% accuracy of the original, pretty epic. The only thing that felt off to me, was the face buttons A B X Y are not 100% the same color opacity of OEM gamecube buttons, but I’ve yet to check if they can be swapped with OEM gamecube buttons. I also want to cover the stupid Old Skool logo with a sticker or something. Even the backside of the controller has the same comfortable rise as the HORI pad.
The original Hori pad was made for use with the gameboy player. I also use it to play Viewtiful Joe and Mr.Driller. It is basically a SNES pad with slightly more textured plastic, raised grip in back, and the iconic gamecube style face buttons. It’s slightly conkier in thickness too.
I also have the raphnet SNES to GCN adapter. Both are valid, and I enjoy them both!
At this point, I think I’ve tried all my favorite GBA classics on gameboy player with one of these controllers. The Hori/Old Skool pad was especially fun for Aria of Sorrow, MK Super Circuit, F-zero…. Actually it’s fun for all of them.
