  • For any machine specific option to take effect, you need to restart the machine (Ctrl+F1), not just to reset it.
  • Most games will not have a problem with the Mega Drive 6-Button Pad. Keeping it enabled will most likely be fine in most cases.
  • The 6-Button Pad in the PC Engine is only supported by newer games. Older games have a real problem with it. Only enable this option when you need it.
  • Memory Card slots 2-4 are currently unused. The only machine to use the Memory Card option is the Neo Geo.
