genesis differences:
Enemies are less agressive but bosses are much harder in later stages, i actually used super attack in the stage 3 boss cause the cycle was infuriating without it and i couldn't find a way to not get knocked down.
Super attack icons are absent in some locations and i couldn't find any replacement for some of them.
new tricks that i haven't confirmed if they're exclusive to the genesis version:
i managed to slam an enemy with Steel and get the other enemy grabbed while the first is still bouncing, lots of damage but doesn't seem practical at all
in stages that have bombs on the floor( red sky) i stepped on them to speed up the cutscene
most of the game is the same the hitboxes and frame data feel a little different but not too much to be honest, the megadrive music is pretty bad also
thanks!
