Rockman 4 STH is one of my favorite games and is much better than Rockman 4 MI. I'm sure you agree too right? Unless you're a Rockman 4 MI fan too. This hack is created by Yosaku, not me and I'm the person that hosted it.
Cossack 2 is a true slippery stage created by Yosaku.
I may end up being in a competition soon when Rockman 4 STH is completed. Keep the news coming.
Cossack 1 BGM is from Rockman 4 Complete Works. Sorry, no boss spoilers.
