Hi, I recently posted this topic in the Classic Gaming forum, and I was suggested to ask about a few certain details of it here. I am aware that in most cases owning ROM copies to play them on emulators is technically illegal (and is in fact only legal if you created the ROM yourself with a legit copy of the game for backup purposes). However, there is a relatively good modding scene within game emulation, as many of you have no doubt seen stuff like incredibly difficult levels put into Super Mario World, and other games. What I am asking is, would it be okay to try what I'm intending to do? What it really is, is just getting a bunch of GR members to work collaboratively on making a version of Super Mario World with all of the levels replaced with new, challenging ones. While it does involve having to have a ROM of the game, an emulator, and a level editor, I figured it would be perfectly harmless seeing as it's not being made to make any money, it is entirely a project for fun. So despite the technically illegal issues at hand, would I be allowed to try for such a project?
