has anyone created (or in the process of creating) a program that tells the user the intructions to most of the games in MAME? i tried searching for something on this site and couldn't find anything. i would like to know so i can decide whether to spend my time trying to build one or so i can see if my attempts would come nothing close to what has already been created. also, would anyone want to use this program in their cab if i built it besides me? if anyone thinks i should go ahead and try to create it i would appreciate any suggestions you have, be they towards the name and what should be included in it or anything else.
