A Technical Analysis of the Non-Merged ROM Set in MAME

Abstract

The Multiple Arcade Machine Emulator (MAME) project utilizes complex ROM management structures to handle thousands of arcade boards, clones, and revisions. Among the three primary ROM set formats—Split, Merged, and Non-Merged—the Non-Merged set offers a unique approach to file organization. This paper provides a comprehensive examination of the Non-Merged MAME ROM set, detailing its file structure, storage efficiency, practical benefits, and drawbacks compared to other formats. The analysis concludes that while the Non-Merged set is the least space-efficient, it offers superior simplicity for end-users, especially those managing small collections or performing manual ROM audits.
