What RomMate is

RomMate is a free, open-source tool for converting, compressing, verifying, and organizing disc images and cartridge ROMs. It converts CUE, GDI, and ISO images to CHD and can extract CHD files to formats including CUE/BIN and ISO. Its README states that CHD conversion can save 40–60% of space. RomMate creates M3U playlists for multi-disc games and checks ROMs against No-Intro and Redump databases, assigning one of five confidence levels from 100% to 80%. It can detect ROM hacks and external copier headers, and uses fuzzy matching to compare filenames and checksums. The project lists support for more than 26 systems across Nintendo, Sega, Atari, Sony, Microsoft, and SNK families, as well as nine languages. Windows and Linux downloads are available as an executable and x86_64 AppImage, both described as requiring no installation. The software is licensed under GNU GPL version 3.0. The v1.2 release rejects Dreamcast CDI conversion because chdman does not support it. The Windows app is not code-signed; a SHA256 checksum is available for download verification.

Who it suits

RomMate is aimed at the ROM preservation community and suits users who need disc-image conversion, ROM checks, or multi-disc playlist organization on Windows or Linux.

What it does well

Free and open source under GNU GPL version 3.0
Checks ROMs against No-Intro and Redump databases
Supports more than 26 listed systems
Windows executable and Linux AppImage require no installation

What to know first

Dreamcast CDI conversion is rejected
Windows app is not code-signed
Linux download is an x86_64 AppImage

Verdict

RomMate brings conversion, organization, and database-based ROM checks together for Windows and Linux. Users should note the Dreamcast CDI limitation and verify the unsigned Windows download with its SHA256 checksum.
