Soul Blade is a pirated port of the PlayStation game of the same name, made for the SNES and Sega Genesis by an unknown developer in 1997. The Genesis version was released as "Soulblade Super" and lacks the "1997 SFC VERSION" text found in the SNES version.
The controls are considered bad, as there is a delay when attacking your opponent.
The fighting engine is recycled from Tekken 2/Tekken 3 Special.
The SNES version only has 6, the Genesis/Megadrive version has only 9.
The final boss in the SNES version is Li Long with a very messy color pallette, the Genesis/Megadrive version only has Cerevantes and Shadow Cerevantes (Who is most likely Souledge, especially Li Long in the SNES version.)
Only the Genesis/Megadrive version can show the normal color pallette of Li Long.
The SNES shows a hint of engrish on the start screen by the words "PUSH START BUTTOM" which is most likely used in Sonic Jam 6.
