Matching MAME Romset: OpenEmu's MAME core is updated periodically. As of recent versions, it uses MAME core 0.250.0.1. If your Metal Slug ROM is from an older or much newer set (e.g., 0.261), OpenEmu may fail to verify or load it.

Missing Dependencies: If a specific file is missing, OpenEmu usually displays an error box naming it. You can use tools like Romcenter to audit your set against a MAME 0.250 DAT file.

Corrupt Saves: Sometimes a game fails to load on the second try due to a bad autosave. Go to Preferences > Library, click Reset warnings, and choose "No" when asked to "Continue where you left off" upon the next launch.

Console Logs: For advanced debugging, open the macOS Console.app, search for "OpenEmu," and attempt to launch the game to see exact missing file names.
