I found my old files of a Megaman Project and decided to share what I've done in the past.
All characters have movement based in Megaman Zero and a simple set of attacks: Buster, Charged Buster, Hyper Move that uses 1 bar. (Except Ashe and Grey, both have only Buster with different settings)
Sorry for not put credit on the custom sprites, I can't remember where I got many of them.
Ps* Megaman Classic sprites were made by myself (S666)
