MarsSeed [1] filed a deletion request for wahcade [2]: Defunct and orphan Python2/Gtk2 based package.
This was a minimal GUI front-end for arcade emulators like MAME. Last released in 2009. I recommend deletion, for lack of interest from anyone in maintaining it, and because there are viable alternatives.
