Tekken 5.1
From Tekkenpedia
Tekken 5.1 was a minor upgrade patch of the original Tekken 5 that was not released on consoles and instead, was only on arcades. It contained various balance changes to characters of the original Tekken 5. The game also tweaked the damage properties for ground moves, instead of ground moves doing 100% damage, they now only inflicted 70% damage. The character health bars for this game sported a different colour compared to the health bars on Tekken 5. (expand on these.)..
