Uh hi I have no idea what I'm doing

I'm drunk off my ass, downloaded Sonic's Schoolhouse because I played it as a kid and it came as an iso, so

How do I like

Make this play

I have to like manually type shit in and that's a pain esp since I don't know anything about how to use this I just wanna play a game lmao, any help here? What exactly do I type in? Also, is there some other kinda dosbox that's easier to use because I can USUALLY figure a computer thing out without having to ask people that's really annoying ok
