You cant map them in the mame input menu?

If your using a keyboard you which you probably are for Mahjong youll need to enable game focus mode.

Youll need to to this for anything if your using the keyboard with as the keys that are bound to the retropad are disabled. So keep this in mind if you want to use even the mame osd the enter key wont work as its bound to the retropad.
