Six Button Control Pad (Mega Drive)

From Sega Retro

Is "Incompatible Games" section for games that don't work on 6-button controller even when holding mode button before startup? Also, I never had problem with playing Golden Axe 2 in 6-button mode. Is this something that happens only on real hardware? Foxysen1 (talk) 11:10, 6 June 2016 (CDT)
