This is what I use. If interested just try googling and see what's available in your region.
For me it works pretty well as the N64 has 6 buttons for fighters and I can switch to the PlayStation pad if I want a different feel.
It might not be the best for everyone, but for what I do, it works really well
I bought two off of Ebay more than 5 years ago. My original is still going strong with the 2nd one still wrapped and sealed for backup purposes if the original ever fails.
