This process ensures your ROMs are clean, complete, and properly named for features like box art and metadata. How RetroArch Verifies Your Games

Database Matching: When you use the "Scan Directory" feature, RetroArch calculates the checksum (a unique digital fingerprint) of your files and compares them against its internal database.

No-Intro & Redump: Most "verified" sets are built using No-Intro (for cartridges) or Redump (for discs) standards. If your ROM matches these exactly, RetroArch will automatically create a playlist with the correct icons.

Manual Scanning: If you have a collection (like a "9000 ROM" set) that doesn't match the database perfectly—such as fan translations or ROM hacks—you should use the Manual Scan option to ensure they still appear in your library. Legal & Safety Notes

Total: ~9,900 games. This collection focuses on Western and Japanese titles (excluding most hack ROMs, prototypes, and duplicates).

Step 3: The "CHD" Conversion Rule

Many "verified" packs include CD images as .chd (Compressed Hunks of Data) files. This is vital for RetroArch. CHD files play perfectly in cores like MAME - Current or Beetle PSX HW, and they save 40-60% space compared to BIN/CUE. If a "9000 verified" pack does not use CHD for PS1/Saturn games, it is not optimized for RetroArch.

Be extremely careful. Many videos or links promising "9000 Roms" are clickbait designed to get you to download adware or viruses.

Avoid .exe files: If a ROM pack downloads as an .exe or .msi installer, do not run it. ROMs are data files (.zip, .7z, .iso, .bin). They should not require an "installation wizard."
Use a Virus Scanner: Always scan archives from the internet before extracting them.
