The primary reason for the enduring popularity of the 0.78 romset is its relationship with . Current versions of MAME prioritize high-accuracy emulation, which often requires significant CPU power. mame 0.78 romset
Furthermore, 0.78 predates many of the internal auditing and renaming conventions that would later complicate ROM management. In subsequent versions, developers would rename files to match original hardware documentation, split parent and clone ROMs differently, and introduce new, more accurate dumps that broke compatibility with older sets. The 0.78 set is celebrated for its "non-merged" structure in many curated collections, where each game’s ZIP file contains all the necessary data to run independently, without requiring a separate parent ROM.
