amxx ver -

I think he wants the mod itself...
Otherwise:
Asskicr posted both versions of his heros if you look at his superhero topics. You might be able to compile amx heros to be used for amxx but not all will work. Best just to wait til jtp updates the amxx ver, cause I think he will convert the other heros to amxx as well (but im not sure). Btw hes waiting for amxx .20 to come out, so don't ask when the next sh for amxx version will be out Im sure he'll let you know.
