Body:
Hi everyone,
I’ve noticed a few requests recently for specific legacy BIOS files, so I decided to upload and share a complete BIOS pack specifically for the MAME 0.147 version.
As many of you know, MAME updates its ROM definitions frequently. If you try to run a game with a newer version of MAME but use old BIOS files (or vice versa), you will often get "Not Found" errors or checksum failures. This pack matches the hashes required for the 0.147 XML driver definitions.
What is included: This pack contains the necessary system BIOS files required to run hardware-based emulators within MAME 0.147 (e.g., Neo-Geo, CPS-2, Naomi, etc.).
Important Note on Compatibility: This set is specifically validated for MAME 0.147. If you are using a newer version (like 0.250+), some of these files will report as incorrect or outdated because MAME developers frequently rename files or discover better dumps. Please ensure your emulator version matches your ROM and BIOS versions for the best results.
Download: (Note: I cannot post direct links to copyrighted BIOS files on this forum due to rules. I have uploaded a text file containing the file names and CRC checks below, or please check the "Archive" dot org link in the comments.)
Helpful Tip: If you are getting errors, try refreshing your ROM paths in the MAME settings after dropping these into your ROMs folder.
Happy gaming
MAME (Multiple Arcade Machine Emulator) version 0.147 is a specific older build (released around 2012) that requires a matching "ROM set" to function correctly. Because MAME evolves, the ROMs and BIOS files from a modern version often won't work with this specific vintage build. Understanding MAME 0.147 BIOS Files mame bios roms 0 147
BIOS files are essentially the "operating systems" for arcade hardware. Without them, even if you have the game ROM, the emulator won't know how to boot the virtual hardware.
For version 0.147, you generally need a BIOS Pack that matches that specific release cycle. Common BIOS files included in a 0.147 set are:
neogeo.zip: Essential for all SNK Neo Geo games (Metal Slug, King of Fighters). cpzn2.zip: Required for Capcom ZN-2 hardware. pgm.zip: For PolyGame Master titles. namcoc7x.zip: For various Namco arcade systems. konamigx.zip: For Konami GX system games. Essential Setup Tips
Matching Versions: Ensure your ROMs are specifically from a v0.147 Reference Set. If you use ROMs from a newer version (like 0.250+), MAME 0.147 will likely report "Missing Files" because file names or structures within the zip files have changed over the years.
Placement: Keep your BIOS files zipped. Do not unzip them. Place them directly in the /roms folder of your MAME 0.147 directory, right alongside your game files.
The "Missing Files" Error: If MAME tells you files are missing even though you have the game, it usually means you are missing the required BIOS zip or a "Parent" ROM (MAME uses a "Clone/Parent" system where clones require the parent zip to run). Where to Find Them
While I cannot provide direct download links to copyrighted ROMs or BIOS files, you can find these archived sets by searching for: "MAME 0.147 ROM set archive" "MAME 0.147 complete BIOS pack"
Look for reputable preservation sites like Archive.org, which hosts many "Rollback" sets for older MAME versions.

The Foundation of Digital Preservation: Exploring MAME 0.147 BIOS and ROMs
The Multiple Arcade Machine Emulator (MAME) project is more than just a tool for playing old games; it is a massive, ongoing effort to document and preserve the internal logic of arcade hardware. Within this ecosystem, specific versions like MAME 0.147
represent significant milestones in the project’s evolution. To understand the importance of this specific set, one must look at the interplay between BIOS files, ROMs, and the strict versioning that governs the world of arcade emulation. The Architecture of Emulation: BIOS and ROMs
At its core, MAME functions as a virtual recreation of physical hardware. For many arcade machines, a single ROM file containing the game’s code is not enough to make it run. Many systems rely on a BIOS (Basic Input/Output System)
, which acts as the foundational firmware used to initialize hardware during the boot process. In MAME, these BIOS files are essentially "system files" that cover the logic of the console or arcade board itself. Without the correct BIOS file—which must typically remain zipped in the ROMs folder
—the emulator cannot simulate the "brain" of the machine, leaving the game unplayable. petrockblock The Significance of Version 0.147
MAME 0.147, released in the early 2010s, is often cited by enthusiasts because it belongs to an era where the emulator’s hardware requirements and the complexity of its ROM sets reached a stable plateau. In the world of MAME, "ROM sets" are not static. As developers discover more accurate ways to dump data from original arcade chips, the requirements for a "complete" set change. A ROM set designed for version 0.147 is a snapshot in time; it contains the specific data structures and file names that the 0.147 executable expects. For users of older hardware or specific mobile platforms, this version remains a "sweet spot" for performance and compatibility. petrockblock The Preservationist’s Dilemma
The reliance on specific BIOS and ROM versions highlights the delicate nature of digital preservation. Because MAME aims for accuracy over speed, newer versions often break compatibility with older ROM sets to accommodate better hardware documentation. This creates a need for "rollback sets" or specialized collections like the Tiny Best Set Important Note on Compatibility: This set is specifically
, which curate specific BIOS and ROM files for handheld devices and older versions of the software. Conclusion
The MAME 0.147 BIOS and ROM collection is a testament to the meticulous detail required to keep digital history alive. By treating arcade hardware as a collection of interdependent data—where the BIOS provides the foundation and the ROM provides the experience—MAME ensures that even as the original circuit boards decay, the logic of the "golden age" of arcades remains accessible to future generations.

In MAME 0.147, the BIOS file format and CRC checks are strict. Using a BIOS from version 0.139 or 0.155 may result in a "ROM mismatch" error.
For better organization, keep all BIOS ZIPs in a roms\bios folder and all game ROMs in roms\games. Update mame.ini accordingly.
Believe it or not, the “obsolete” 0.147 BIOS set is perfect for:
By default, MAME (the command-line version or MAMEUI) uses a folder named roms inside its installation directory. If you use a frontend like QMC2 or LaunchBox, you may have set a custom path.
Cause: Missing BIOS ZIP, or the ZIP has the wrong internal contents.
Solution: Ensure you have, for example, neogeo.zip in your roms folder. Open that ZIP and verify it contains files like sp-s2.sp1, usa_2slt.bin, and vs-bios.rom (names will vary by version). For 0.147, a valid neogeo.zip should be around 1.8 MB.
