This may or may not require the DLC, it definitely works with it. Doesn't have any of the pretty effects, but super powers are all there. Equip the apoca fist for best results. Fair waring, I'm unsure if the variables are saved with game save, so it may be more work than deleting files to revert save to normal. Won't work with weapon upgrades for the fireball/electric ball, if you want to downgrade weapons just empty the contents of the upgrade table.
The bulk of this is one line in the main function.
player_super_powered(LOCAL_PLAYER, true)
This enables the Hadoken animation, super speed, running through cars, damage resistance, and no rag doll.
The rest is flavor of creating the fire and energy grenades that act as rockets. Without the resources preloaded I couldn't get a quite proper audio noise.
