**Method A:
Setting up MAME 0.239 (released in late 2021) follows the same core principles as most modern versions, but requires a specific "0.239 ROM set" to ensure 100% compatibility. Here’s a quick guide to getting your arcade library up and running. 1. Match Your ROMs to Your Version

files directly. Do not extract them into individual folders unless you have a very specific reason to do so. 2. The Standard Installation Path

After dropping your files into the folder, MAME might not see them immediately. Open the MAME UI. "Available" on the left sidebar. If they don't appear, press (or select "Refresh") to trigger a directory scan. If a game won't launch, use the command line mame -verifyroms [gamename] to check for missing files.

To install MAME 0.239 ROMs, you must place your zipped ROM files into the roms folder within your main MAME directory. It is critical to use a ROM set that matches your specific MAME version (0.239) to ensure compatibility. Core Installation Steps
Locate the ROM Folder: Navigate to the directory where you extracted MAME 0.239. Look for a folder named roms.
Add ROM Files: Move your downloaded game files into this folder. Keep them in their .zip or .7z format; MAME is designed to read them compressed. Handle CHD Files (Hard Disk Images):
For games requiring large data files (CHDs), create a new subfolder within the roms directory.
Name this subfolder exactly the same as the ROM zip file (e.g., for kinst.zip, the folder must be named kinst). Place the .chd file inside that specific subfolder.
Refresh MAME: Launch mame.exe. If the games do not appear, go to General Settings > Audit All Games (or press F5) to let MAME scan the new files. Configuring Custom Directories

2. Locate your roms folder

3. Copy the ROMs
4. Verify with MAME Launch MAME 0.239, press Enter on “Available”. If a game is missing a BIOS or parent ROM, MAME will show a yellow or red warning. Use the built-in Audit feature (right-click a game → Audit) to check for missing files.
