Few legitimate sources offer this due to copyright. Some "MAME builds" from 2010 included BIOS files, but most modern emulation frontends (RetroArch, LaunchBox) require you to supply your own.
Enjoy! EXTRA NOTES: If you use this MAME xml like a "master" in your HyperSpin installation (because you have all this 0.139 roms) HyperSpin Home
Remember: Always scan your downloads with antivirus software and support arcade preservation by owning the original PCBs when possible.
Distributing copyrighted BIOS files is illegal in many jurisdictions. BIOS files are typically dumped from physical arcade hardware, which you must legally own. This article is for educational purposes.
