This one is a little odd. The title implies that it is an arcade game emulator, once installed the icon says Super NES, and once you play it you find it actually contains 69 Nintendo Entertainment System games. The opening screen contains game icons with, I believe, Japanese titles. There are some Japanese games but most are in English.
The emulator itself works pretty well with save and load states and the onscreen controls are well placed.
