The Marvel Super Heroes remake by SpiDoL is a decent effort developed with the MUGEN game engine.This remake is as good as it gets, It makes the player feels like it is playing in a arcade machine.
Most of the standard and special moves from the arcade version have been retained, hence veterans should be able to figure out the controls in no time. Some of the new characters are pretty fun to play with as well. A simultaneous team mode also allows all four combatants to slug it out at the same time.

Authors Note :
Also, there's a hidden character in the game: the Sentinel. Here's how to unlock him:
Open up "data\select.def". Scroll down until you see:
drdoom, stages/....
randomselect
thanos, stages/....
Replace that randomselect with:
0senti, random
And you have the Sentinel!
