Does anyone know of an active, safe source for the 0.37b5 set in 2025? Or tips on converting a newer set backwards?

Before you go searching for a “MAME 0.37b5 ROM set,” here are a few important things to keep in mind:

I’ve been getting back into retro arcade emulation, specifically using older versions of MAME that run well on low-end hardware (like the Raspberry Pi 1/Zero or classic Xbox). The version I’m targeting is , which is the basis for MAME4ALL and similar builds.

If you already have a newer set, you can’t just downgrade. But tools like ClrMAMEPro or ROMVault can rebuild a set if you have a dat file for 0.37b5. The dat file defines what the emulator expects.

Thanks!

Please only download ROMs for games you physically own, or stick to homebrew / public domain titles. I can’t share direct links, but I’m happy to help with technical advice on matching ROMs to your version.
