Mine didn't have a name, but it was pretty much a SMW that tried to piss people off, like randomly cutting off ground so you would fall through unexpectedly. It was hell. I just kept working on hacks until I made some stuff that could stand presentable among other hacks. That was years after of course.
Mine was Super Insane Mario World. I managed to complete one world+one extra level before stopping. It wasn't all that great, mostly just a bunch of level edits, complete with floating munchers and an overload of Yellow ! blocks, cement blocks and used blocks, and its still on the computer (all of my hacks are still on the computer actually)
---------------- Red Tales: [Insert Subtitle here]: Hack is being worked on, will be finished who knows when
Levels Complete: 5/50+
The first official SMW hack I've made was my current one, SMW2+3: The Essence Star.
The first one technically I ever released was SMW+ seven years ago, but that was a very crappy hack. I did have another SMW hack before that one that was nearing completion, but then I corrupted my ROM by improperly inserting ExGFX to the ROM. Ah well.
