hi all. 

well i dont know if you all already know this (the topic in there is a little old, so if the answer is "yes", please erase this post), but the thing is that i are one of the menbers of "streets of rage remake website" (cabo-hicks in there).
 
so, well its supposed that with all the info in there, and in streets of rage online website, we must know all about sor series...

BUT NOT!, i see this screenshot today (see the forum for see some few shots with 2 really rare new enemys or early style, and even one rare stage with buildings never seen. whoa!)

the forum with more info or pictures here (best see all the pages):

these of course are a bare knuckle 1/streets of rage 1 beta. 
interesting right?

even they make the recreation of these sprites with more quality than the poor screenshot quality as firm of one of the menbers.
