Seems to work on the SNK games. Need to see what they have in common. But yes, it works.

what does SNK stand for?

lol SNK is the publisher. Games such as Metal Slug, Samurai Showdown, Fatal Fury, King of Fighters, so on and so forth. Sorry, I'm an 80's baby from the "Arcade Era".

As stated early, I've only gotten this to work on most of the live arcade games that are published by SNK, but that's about it.

o ok
