What RomMate is

RomMate is free, open-source software for managing disc images and cartridge ROMs on Windows and Linux. It converts CUE, GDI, and ISO disc images to CHD, and can extract CHD files back into formats such as CUE/BIN and ISO. The README reports 40–60% space savings for CHD conversion. For multi-disc games, RomMate creates M3U playlists. Its verification tools compare ROMs with No-Intro and Redump databases, using five confidence levels from 100% to 80%. The software can detect ROM hacks and external copier headers, and uses fuzzy matching for filenames and checksums. Support covers 26+ systems from Nintendo, Sega, Atari, Sony, Microsoft, and SNK, with nine listed languages. Windows and Linux downloads require no installation. The Windows app is unsigned, with SHA256 verification available on the release page. Dreamcast CDI conversion is rejected because chdman does not support it.

Good

  • Converts CUE, GDI, and ISO images to CHD
  • Extracts CHD files to CUE/BIN and ISO
  • Creates M3U playlists for multi-disc games
  • Checks ROMs against No-Intro and Redump
  • Supports 26+ systems and nine languages

Watch out

Who it suits

RomMate suits ROM preservation users who need conversion, compression, verification, and organization tools across Windows or Linux. It is particularly relevant for multi-disc collections and users checking files against established databases.

Verdict

RomMate combines CHD conversion, ROM verification, and collection organization in a free, open-source package. Its unsigned Windows download and unsupported Dreamcast CDI conversion are important considerations.
