If you try to load a ROM file meant for a modern version of MAME (e.g., v0.280) into an older MAME 0.72 emulator, it will almost certainly fail to work. This happens because:
The most significant hurdle is memory. On the original Xbox, the MAMEoX 0.72 port lacks VMM (Virtual Memory Management). This technical limitation means that while smaller Neo Geo games will run perfectly, larger titles like Metal Slug 3 or The King of Fighters 2002 will likely run out of memory and crash. mame 072 roms
The ROMs tied to this version are therefore a "frozen snapshot" of that golden compatibility. A complete MAME 0.72 ROM set—typically around 12 to 15 gigabytes—contains roughly 2,000 to 3,000 unique games. These are not necessarily the most accurate dumps, but they are the most famous dumps. Here, you will find Street Fighter II with its audio perfectly intact. The Simpsons arcade game runs without graphical glitches.

And as long as people want to hear the coin-drop sound and see the "Insert Coin" screen flash, those specific, imperfect, wonderful keys will continue to turn.
