Fast Switch Note: On games with spinners, lots of standup targets, or rapid switch sequences, PinMAME timing may miss inputs — this is a software emulation limitation with no current fix. LISY35 SMD is best suited for diagnostics and bench work via the LISYcontrol web interface. For daily gameplay, SternFA (hardware emulation) is the recommended choice.
Note: On spinner-heavy games, fast switch inputs may occasionally be missed. BallyFA (hardware emulation) is recommended for those titles.
