What it is
RomForge is free, open-source desktop software for managing ROM collections in the OfflineList DAT ecosystem. It scans ROM folders and matches files to DAT entries using CRC32, then reports statuses such as Verified, Missing, Incorrectly Named, Wrong Archive Type and Untrimmed. Users can rename ROMs to DAT-expected filenames, re-archive between ZIP and 7z, and remove GBA or NDS padding. The application supports multiple DAT files and can update them from configured URLs. Its cache re-hashes only files that changed, while game-list status persists across restarts. RomForge is a modern rewrite of OfflineList and remains compatible with community DAT files. It reads OfflineList XML DAT files, which users supply, but does not currently read the No-Intro/Logiqx format. Supported systems are macOS on Apple Silicon and Intel, Windows x64 and Linux x64. The macOS app is signed and notarized; Windows downloads are ZIP archives and Linux downloads are TAR.GZ archives. The project uses the MIT license.

Strong points and limits
Strong points
- CRC32 matching verifies ROM files against DAT entries
- Renames files to DAT-expected names
- Re-archives between ZIP and 7z
- Cache re-hashes only changed files
- Supports macOS, Windows and Linux
Limits
- Does not read No-Intro/Logiqx DAT format
- Users must supply DAT files
- Only the latest release receives security fixes
- Linux downloads are TAR.GZ archives
Who it suits
RomForge suits ROM collectors who organize files with OfflineList XML DATs on macOS, Windows or Linux. It is useful for users needing hash verification, renaming, archive conversion and status tracking.
Verdict
RomForge provides a focused OfflineList workflow across three desktop operating systems. Its main boundary is DAT compatibility: it currently reads OfflineList XML, not No-Intro/Logiqx files.
