MFME 20.1 does not come with game ROMs. You download the emulator shell, then separately download "layouts" (DXF or .fml files). The emulator community does not distribute the actual machine ROM code; users must find or dump their own, which is why the software remains legal to distribute.

| Problem | Solution |
| :--- | :--- |
| "Component 'MSCOMCTL.OCX' missing" | This is an old Visual Basic runtime error. Download the official MSCOMCTL.OCX fix from Microsoft or the Fruit-Emu forum tools section. Register it using regsvr32. |
| The machine loads but reels don't spin | You are missing the ROM files for that specific MPU. Check the layout's readme. Some layouts require you to source the ROMs separately (rare for full layouts). |
| No sound / crackling sound | Go to Options > Audio Settings and change the "Latency" to 30ms or 40ms. Also, ensure your Windows sound format is set to 44100 Hz (Studio Quality). |
| The window is too small | Press F11 for fullscreen or use the View menu to scale to 2x or 3x. MFME 20.1 supports smooth scaling. |
| Layout says "Unsupported ROM board" | You have an older layout built for MFME v5 or v10. Use the "Layout Converter" tool included in the MFME 20.1 tools folder to update it. | MFME 20
