Getting Started with MAME

Back to the Top

Configuration

Back to the Top

• Config Location: /home/deck/.mame
• Storage: /Emulation/storage/mame
  • Contains: artwork, ctrlr, ini, and samples
• ROM location: /Emulation/roms/arcade

Note:

• ~/.mame is an invisible folder by default. In Dolphin (file manager), click the hamburger menu in the top right, click "view hidden files" to see these folders.
• Mame [Standalone] shares its /Emulation/roms/arcade folder with Arcade - RetroArch MAME Current. Turning both of these parsers on in Steam Rom Manager will cause duplicates in your App List.

Maintaining ROM Versions

Back to the Top

Ideally use ROMS that are the same version as MAME's version. MAME often releases improved versions of ROMS to fix issues. Issues are less of a concern with the most popular classics because most of those haven't changed in years. But to avoid having to track multiple different versions of your ROMS, most people just keep their romsets updated as the emulator updates.

To understand how MAME works, look up the difference between merged and split ROM sets, and learn what a sample and a chd are and how they're used in conjunction with roms to deliver a playable game.

Note: Refer to https://docs.mamedev.org/usingmame/aboutromsets.html, for additional information.

How to Add Custom Bezels

Back to the Top

1. Open Emulation/storage/mame
2. Copy bezel files, in .zip format, into this folder, named the same as the rom.
3. Done.

Note: Use the Bezel Project to locate bezels for your MAME ROMS: https://github.com/thebezelproject/BezelProject-Windows
