@mitu Thanks for your reply, I think I will try to create my own smash Bros

I might be a homebrew clone of the game, or a self-extracting archive. Where did you get it, @Dresher?

However, exe files are binary files for Windows or MS DOS and can't be "made" into other extensions.

(At first, I wondered what a "game stacker" might be. 😊)

@cybermonkey01 most of the free to download games that can run on the pi are already in our ‘ports’ package manager.

It's likely you could get it to run through Wine. Normally, this wouldn't be recommended, as the results would be pretty slow. However, a basic editor like PKHeX might run decently well. Rather than point you to a single tutorial out of so many, do a Google search for "wine on raspbian" and just pick one that suits you.
