Just because MAME supports it doesn't mean you can play it online. In fact, just because MAME says it can support it doesn't mean you can play it in MAME.
MAME supports just over 8,000 games. about half of them are duplicates meaning there is about 4,000 unique games. Just over 1,000 of those 4,000 do not work. About 50 of them are not even games. So MAME plays a little less than 3,000 games.
We use a customized version of MAME that supports 2,669 games - no duplicates or broken games or non-games. So about 350 less than the official MAME. About 200 of those 350 are CHD (Compressed Hunks of Data - Hard Drive or CD) games which are larger than CDs which would take forever to load and we couldn't afford the bandwidth or disk space.
We have put just 1,953 of the 2,669 possible Coin-Op games online. Of those 1,953 we have removed 2 because of errors. Sonic and Altered Beast.
That means only 716 more Coin-Op games could be added. But all of those are over 10MB each which is really pushing online capabilities. 527 of them are over 20MB which is not going to happen. So that leaves about 189 games that are almost too big (10-20MB) but might be added next year.
Those 189 games that could be added next year are listed below. No other Coin-Op games will be added. So requests will be ignored. These are sorted by size. The top of the list is 10MB - about the size of
Super Puzzle Fighter II Turbo. The bottom of the list is 20MB about double the size of SFII. The load times of the games at the bottom might be too long to add.
