Well if it is a full set you would have all you need for most games (roms and bios) with the exception of those games that need a CHD. Getting a full Mame set from some place well known is always the best. Then you have to hunt down a bios or other supporting file that you many times do not know you need until you try to play the game. Also all these random sites that house roms, you never know what else they inject into the file. Thing about doing it piece by piece is you do not know what version Mame that rom is for, most will work fine over the versions, but still can be an issue. We did not specifically say don't, we just recommended not to do so. I suppose I will need to figure out how to get PD working if that is best way to ensure I am getting the right stuff. I know you guys said don't piecemail it, but I would rather not spend days download 5000+ games when I really only want like less than 100 which are mainly fighting games. Most of the Capcom games work now though since I was able to get the proper qsound among the downloads.

So I rolled back to that version and then downloaded all the roms and chd files that I think I need, but there are still several games that are greyed out and don't work in MAME itself. So I found a full set that is supposed to be for v 0.202 of MAME.

That will usually make sure you get the version you need) (as a pure example, if your missing roms for a game, lets say tron.zip and its says you are missing pro0.d2, search for that, not tron.zip. If you decide to update, sometimes sites like Pleasuredome don't always work well for some, you can just google for the specific name of the rom you are missing, you'll find a link fairly easily. If you are happy with the MAME roms you can play in OpenEmu, you can download MAME 0.149 from and use that version and your current roms will work. This does not mean it isn't good, it just might not run some newer games that have been added since. I just checked OpenEmu on my Mac and it us using MAME 0.149, so it's fairly old in terms of MAME. In this case back at version 0.182 i think it was the qsound bios was changed, so if your roms are older than 0.182 then you have to use a version of the emulator prior to 0.182 also. This is why MAME has versions, not all roms will work with all versions of the emulator as the files change. It would be easier for you to use a older version of the MAME emulator.
