This one was the best I came up with. All I did was open the rom file up in EditPad and copy and paste random chunks of code from one end of the file to the other, and all of a sudden, Super Mario Bros. became a very different game. Check it out, if you like -- FCEUltra gives the best results.
Please don't ever play it if you're at risk for seizures, though. I'd feel really bad if I killed you with a rom hack.

The king of all corrupted Mario hacks is still Proceduralglitch3.nes, though. I don't remember who made it, but I got it off of an old thread at selectbutton.net. It turns Super Mario Bros. into a race against impending and inevitable doom, as levels will gradually become more and more corrupt over time. As the glitches become more severe and the level layouts become less visible, it often becomes a desperate, blind struggle to find a warp pipe or finish a stage before the game crashes. It tests your familiarity with Super Mario Bros. in new and unexpected ways, and never plays the same way twice. I like it a lot.
Also I have a twitter now, for whatever that's worth. I still don't really know what to do with it.

SMB was very very susceptible to game genie foolin', too. most be something of a volatile game or something. i still remember one of the best codes i ever found for it: AAAPON, which replaces all the enemies in 1-1 with different ones (cheep cheeps!) but unfortunately it only works in 1-1. i never was able to make it do anything else.

This reminds me that I need to do some sort of writeup about Skate Kid Bros. It's your average nonsensical graphics hack for SMB... except it actually got released in arcades somehow! You start off as a kid on a skateboard, then when you pick up a quarter (the magic mushroom replacement, which actually says "25C" on it like all quarters do), you transform into your big brother!.... what?

Goombas are replaced by... tanks. Grab that quarter!
Hammer brothers are... ninjas. With green belts.
Bowser is..... a football player?!
maaaan I don't fucking know

I actually PLAYED that as a kid so many years ago!
... And if memory serves me right (which it may not), said arcade was at a skating rink. Kinda appropriate, eh?
Wow, thanks for unlocking this old memory!

I remember playing your ROM hack at SGE. It was hilarious.
Good to hear from you Danny, it's been awhile. I bet you'll enjoy Persona 3. Don't play "The Answer" though, if you got FES. It's garbage. If you must see the rest of the story, do as I did and cheat your way through it.

Also: That rom hack is FUCKING RADICAL

Also, SMB is really stable. The only things that usually crash it are Sprite 0 missing the background; other than that it's somewhat amazing.

I remember playing proceduralglitch3 and the ROMhacks you guys made at SGE- rad indeed! Those were crazy challenges.
Also, yeah, I went ahead and made a Twitter as well. I guess that makes me really cool/totally lame.
