itch.io

probably not. but thats just a guess based on how cool it is

judging by the fact that it uses assets from the games themselves, i'm gonna assume it's free. i mean, not only'd it be kind of a dick move to ask people to pay for it, and not only is literally every other case-making tool out there free, but capcom is PROBABLY not gonna like it either

Yes. 

As it's a fan game using properties owned by Capcom, GamTam legally cannot  charge money for this.
