A friend helped me find the hacks and apply them to Super Mario World, which then added functions and changed the world.

As you can see it's very different. There are new thingies too such as these grey ? blocks that put things straight into your storage box; even shell men!
Um. Odyssey has more functions because it is newer. There are blocks that only monsters can go threw and stuff. There's a lot more, I just haven't gotten that far yet.
An Odyssey level.
They're a challenge and just awesome if you loved Super Mario World.
To apply the cracks you'll need a few Lunar programs and the original SMW rom, and to play them you might want ZSNES.
