0139u1 Roms List — Mame

Introduction
The MAME (Multiple Arcade Machine Emulator) project preserves arcade gaming history by emulating arcade hardware and grouping associated software — ROMs — into organized sets corresponding to specific MAME releases. The MAME 0.139u1 release is a historical snapshot reflecting the state of supported games, clones, BIOSes, and dumps at the time. Studying its ROMs list reveals not only which titles were playable then, but also insights into preservation priorities, legal and ethical issues, and the evolution of emulation practice.

Historical context and significance
MAME’s versioning marks incremental additions and fixes. Version 0.139u1 (a "u" update) sits within an era when arcade preservation accelerated: more systems were supported, accuracy improved, and contributors increasingly focused on documenting hardware specifics. The ROMs list from 0.139u1 captures contemporary knowledge — which boards had available dumps, which regional versions existed, and which hardware variants remained undocumented.

Structure and content of the ROMs list
A typical ROMs list for a MAME release enumerates entries grouped by game/driver name and includes:

From 0.139u1’s list you’d expect to find examples across popular manufacturers (Capcom, SNK, Namco, Sega, Taito) and hardware platforms (CPS-1, Neo Geo, System16, etc.), plus numerous lesser-known or bootleg titles. The presence or absence of certain systems reveals where archival effort had focused and where gaps remained.

Preservation and technical accuracy concerns
Analyzing a release’s ROMs list illuminates preservation quality:

Legal and ethical considerations
The ROMs list itself is documentation; however, distribution and use of ROMs often implicate copyright. MAME’s community emphasizes preservation and historical study, but end users must respect legal constraints in their jurisdictions. When interpreting a ROMs list, researchers should separate technical analysis from distribution or use recommendations. mame 0139u1 roms list

Conclusion
The MAME 0.139u1 ROMs list is a useful historical artifact reflecting the state of arcade preservation and emulation at that release. Studying it reveals which titles and platforms were supported, the completeness of dumps, and organizational practices (parent/clone relationships, BIOS sharing). For researchers and preservationists it provides technical metadata for verification and reconstruction, but should be used with awareness of legal constraints and the fact that later MAME releases will contain more complete and corrected data.

This version supported early Naomi emulation via dc.zip (Dreamcast BIOS).

MAME is a constantly evolving project. Developers frequently rewrite the code to emulate hardware more accurately. While this is great for preservation, it often breaks compatibility with older ROM files. A ROM that worked perfectly in version 0.100 might not work in version 0.200 because the emulator now expects different file structures or names.

MAME 0.139u1 (an update to the 0.139 baseline) is widely considered a "sweet spot" for several reasons:

Since the full MAME 0.139u1 set contains thousands of files, manually listing them all in a text file is impractical for a forum post. However, you can generate or view the full list yourself using these methods: Legal and ethical considerations The ROMs list itself

Between MAME 0.100 and 0.162, the MAME team released "U" updates frequently (sometimes daily). These were bleeding-edge builds. 0.139u1 specifically was released in March 2010.

MAME 0.139u1 uses a strict parent/clone system.

If mslug3.zip fails, ensure mslug.zip (Metal Slug 1) is not required as a parent. In 0.139u1, Metal Slug 3 was still a standalone clone of mslug.
