Cause: Old MAME 32 uses DirectInput 7, not XInput (Xbox controllers). Fix: For USB gamepads, go to Options > Default Game Options > Controllers. Enable "Joystick Input." If using a modern Xbox controller, you need a wrapper like x360ce (vintage) or stick to USB retro pads like the Gravis GamePad Pro.

This is the holy grail for old PC users. It is tiny (approx 1.5MB), runs on Windows 95, and supports 2,500+ games. Search for the installer on archive.org or retro-specific repositories. Look for files named mame32b.37b5.exe.

Cause: Old MAME 32 does not automatically throttle to CRT refresh rates. Fix: Press Tab during gameplay. Go to Slider Controls. Reduce "Overall Speed (%)" to 100. For flickering, enable Triple Buffering and Wait for Vertical Sync in the Video options.

Cause: Old arcade machines used analog samples, not digital sound chips. Fix: Find a "samples pack" for MAME 0.37b5. Place the unzipped sample folders into your samples directory. In MAME 32, go to Options > Default Game Options > Samples and ensure "Play Samples" is checked.
