-Cyriss Going forward just remember to show " *runahead option must be set to off and shown in video " when using Retroarch and then this screen below with the Race Mode and Difficult. The Runahead option should be found in the Retroarch Settings Menu under Latency. Appreciate your time and I can't wait to see more!

Runner notes: RETROARCH MAME (2010) + HORI FIGHTING COMMANDER. Game Settings shown below.
