Installing ROMs for MAME 0.239 follows the standard procedure for recent builds, though this specific version introduced significant fixes for Philips CD-i and Yamaha FM synthesis. To get your library running correctly, you need to match your ROM files to the version 0.239 data set and place them in the correct directories. 1. Basic Installation (Standard ROMs)
Locate the ROMs Folder: By default, MAME looks for a folder named roms within its main installation directory.
Add Your Files: Drop your zipped ROM files directly into this folder. Do not unzip them; MAME reads the contents from the .zip or .7z archives.
Verify Compatibility: MAME versions are strict about ROM sets. If a game doesn't launch, it’s likely because the ROM version doesn't match 0.239. You can use the command mame -verifyroms to check if your files are valid for this build. 2. Installing Games with CHDs (Hard Disk/CD Images)
Version 0.239 includes improvements for CD-based systems like the Philips CD-i. Games for these systems often require a .chd file.
Create Subfolders: Inside your roms folder, create a new folder named exactly after the game's short name (e.g., for NBA Showtime, name it nbagold).
Place the CHD: Move the .chd file into that specific subfolder. The main ROM zip file should still stay in the root of the roms folder. 3. BIOS and Device Files
Many arcade and console systems (like the Famicom Disk System, which saw updates in 0.239) require BIOS files to boot.
Installation: Treat BIOS files (like neogeo.zip) just like standard game ROMs. Keep them zipped and place them in the root of your roms folder. 4. Configuration and Paths mame 0239 roms install
If you want to store your ROMs on a different drive, you must update MAME's configuration:
Generate an INI: If you don't see a mame.ini file, run mame -createconfig in your terminal or command prompt while in the MAME directory.
Edit rompath: Open mame.ini and locate the rompath line. You can add multiple paths separated by a semicolon (e.g., rompath roms;D:\Arcade\ROMs). Troubleshooting
Audit Your ROMs: Use a tool like ClrMamePro with a 0.239 DAT file to ensure your ROM set is complete and correctly named.
Legal ROMs: You can find a small selection of legal, free-to-distribute ROMs on the official MAME website.
