This project is a WIP. The dat format, headers and content are subject to change until the initial release is published. Use at your own risk.

ENTrimmed is a curated DAT collection project focused on building practical ROM sets for retro gamers. It emphasizes English-speaking region preference, retail-only games, and a strict 1G1R (1 Game 1 ROM) format. The goal is to produce ROM libraries that are ready to play and free from clutter.

Project Goals

• Remove hacks, prototypes, homebrew, aftermarket releases, and other non-retail ROMs.
• Prioritize English-speaking regions.
• 1G1R Format.
• Built from official DAT sources (No-Intro, Redump).
• Compatible with ROMVault, ClrMamePro, and other DAT managers.

Tools Used

ENTrimmed uses open-source, community-trusted tools for building and verifying sets:

• Retool – For generating 1G1R trimmed DATs
• ROMVault – For scanning, fixing, and validating
• DATVault – For sourcing No-Intro, Redump and T-En DATs

Naming & Structure

ENTrimmed DATs follow a consistent naming convention:

System (1G1R Retail English + T-En) [ENTrimmed].dat

The "System" component of each filename is defined as per the LaunchBox database naming.
