As a joke when a new version happens I usually scroll down to the M section to see if Marble Madness II finally got added and was surprised to see that the Marble Madness set itself wasn't in my gamelist (using EmuLoader as a front end). It also doesn't show in ARCADE64 but in MAMEUI it does and will work if chosen but it gives a LUA error before starting the game.
Just wanted to give a heads up to the team (as well as all the posters) to whom I wish a Happy New Year.
