Problem with kawaks

[best4ever20]

Im trying to play a game called megaman 2: (US random number) however when I try top change the files´ name to that it says files can not include : what do I do?

Filenames in arcade emulators have short names, such as megaman.zip or something like that. Look in Kawaks' games list what the short name is. IIRC it's the last column.
