In the list of hacks for a game, there is a column that says "Mods" and lists various letters: G, L, T, S, and GP. Do they have a specific meaning? I thought maybe they stood for Graphics, Title, Sound, and Gameplay? I'm looking at Super Mario Bros 3 if that makes any difference. Sorry if this is answered or listed some where on the site, I have poked around but was unable to find this information.

Thanks for any answers!
