I need one because the current builds run slower then shiz on my PC. Anyone suggest a good working MAME with a link to the download.

Also an older build that will not only run on my weak PC but play most games still even to this day. I mainly want beat em ups!

Won't do you much good without older ROMs too. You'll need to look for a "Rollback" torrent to correct the ROMs.

As for the emulator, Joymonkey has an archive.

Sometimes it helps to read the stickied topic too...

Tell me more about this "Rollback" please.

just get clrmamepro and a dat to match your older mame builds. Import the dat select your rom path and output path . presto old mame set. I've never used rollbacks or a program to use roll backs but clrmamepro has tons of good features.
