Title: Diving into the MAME 2000 Reference Set – Is MAME 0.37b5 Still the King of Low-Power Emulation?

Body:

Alright, let’s talk about a classic that refuses to die: the MAME 2000 Reference Set (built around MAME 0.37b5). MAME 2000 Reference Set - MAME 0.37b5 ROMs and ...

For those new to the scene, back in the early 2000s, this version of MAME was a turning point. It wasn't the newest back then, but it became the gold standard for emulation on underpowered hardware. Fast forward to today, and the "MAME 2000 set" (0.37b5 ROMs) is still the go-to for:

Why 0.37b5? ✔ Incredibly lightweight – Runs full speed on a potato. ✔ Huge library – Focuses on golden era arcade games (late '70s–mid '90s). Think Pac-Man, Donkey Kong, Street Fighter II, Metal Slug (most of them), Neo Geo classics. ✔ Stable reference set – Once you have the "MAME 2000 Reference Set," you know every ROM matches the emulator perfectly. No guessing about versions.

The catch (and it’s a big one): ❌ Accuracy is rough by modern standards. Sprite layer glitches, missing sound effects, and incorrect emulation details are common. ❌ No CHD support (so no hard drive based games like Killer Instinct or later fighters). ❌ Many games from 1997+ are broken or missing entirely.

My experience: I recently dug out an old Pi 1 Model B and loaded up the 0.37b5 reference set. Honestly? For a nostalgia cabinet running 80s and early 90s games, it’s flawless. CPS1, CPS2 (with some rom tweaks), Neo Geo – all buttery smooth. But trying to run Battletoads arcade or Raiden Fighters? Nope. Crash city.

Question for the group: Are you still using MAME 2000 / 0.37b5 in 2025? Or have you moved up to MAME 2003 Plus or even FB Neo?

Also – does anyone have a good source for the exact dat file for the "MAME 2000 Reference Set"? I’ve got a mixed ROM folder and want to audit it against the original reference. Title: Diving into the MAME 2000 Reference Set
