The Ultimate Guide to the MAME4all 037b5 Complete Romset (2270 Games)
If you are into retro gaming on low-power devices like the Raspberry Pi Zero, older Android phones, or the Dingoo A320, you’ve likely crossed paths with MAME4all. While modern MAME has moved far beyond it, the 0.37b5 romset remains a "gold standard" for performance-focused emulation.
In this guide, we’ll break down why the "2270 new" romset is still relevant and how to get it running perfectly. What is MAME4all 0.37b5?
MAME (Multiple Arcade Machine Emulator) updates its versioning constantly. However, as the emulator becomes more accurate, it requires more processing power. MAME4all is a high-performance port based on the very old MAME 0.37b5 engine (released circa 2000).
Because it is optimized for ARM processors, it is the default choice for: Raspberry Pi 1 / Zero (using RetroPie’s mame4all-pi) Classic Handhelds (BittBoy, Miyoo Mini, PocketGo) Older Android devices Why "2270 New"?
The original 0.37b5 set contained fewer games. Over time, enthusiasts have cleaned up, verified, and supplemented the set to include approximately 2,270 ROMs. This "complete" version ensures you have all the supported clones, regional variants, and parent sets that the MAME4all core can actually handle. Key Features of the 2270 Romset
High Speed: Unlike newer sets (like 0.139 or 0.78), these games run at full speed on hardware with limited RAM and CPU. The MAME4ALL 0
Small Footprint: The entire collection is significantly smaller than modern sets, making it perfect for 8GB or 16GB SD cards.
Stability: Because the 0.37b5 core is no longer changing, once you have the correct romset, you’ll never have to worry about a "broken" game due to an update. How to Install and Use the Romset 1. Match the Version (Crucial!)
MAME is notorious for being picky. You cannot use a MAME 0.250 romset with a MAME4all 0.37b5 emulator. If the versions don't match, the game simply won't load. Always look specifically for the "0.37b5" label. 2. The ROM Folder
On most systems (like RetroPie or Recalbox), you will place your zipped files into the following directory:~/RetroPie/roms/mame-mame4all/ 3. Handling Samples
Many early arcade games (like Donkey Kong or Galaga) used discrete audio circuits that aren't easily emulated. For these, you need a Samples pack.
Place these .zip files in the samples folder within your MAME directory. Do not unzip them. Performance Tips for MAME4all
Smooth Scaling: If your screen looks "shimmery," check your emulator settings for "Video Scaling." Set it to "Integer Scale" for the crispest pixels.
Overclocking: If you are using a Raspberry Pi Zero, a mild overclock can help with more demanding games like Mortal Kombat or NBA Jam.
Controls: MAME4all usually maps controls automatically, but you can press the TAB key on a keyboard once a game is launched to remap your buttons. Verdict: Is it still worth it in 2024?
Absolutely. While it doesn't support 3D arcade games or the latest "perfect" emulations, the MAME4all 0.37b5 2270 romset is the undisputed king of efficiency. It turns a $10 micro-computer into a powerhouse arcade machine capable of playing nearly every classic from the 70s, 80s, and early 90s.
