I've been working on this the past few months, adding features and things. I finished everything for a 1 world demo a few days ago, and have been fixing bugs since. I finished a playthrough without issues tonight, though I'm certain there's still bugs in there somewhere. Anyway, screenies:

Features:
- Custom levels designed by me (duh)
- Custom graphics (also duh)
- Custom music (though only one song ported by me)
- Custom blocks, such as the SMB3 breakable brick, and falling donut blocks (more duh)
- Assembly hacks, including custom sprites, level behavior, graphical effects
- Custom bosses that make use of pretty much all of the above.
- 8 total levels, with 12 exits to find.
Story:
In a Mario game? Seriously, Mario games never have much more story than "save the princess from Bowser." You have to wonder if she's getting kidnapped on purpose just to get away from him...
General stuff:
- No yoshi (yet). He's too powerful, I think, so I'm going to save him for later in the hack
- Capes are rather rare, since they're also powerful. I may get rid of them entirely except out of green switch blocks. Not sure yet.
Known issues:
Two places have nasty status bars. (These have never been a huge priority on my fix list, and I didn't want to delay my demo any longer)
So yeah... 1 world demo. I'm going to port everything over to a new rom, so any bugs you might find would be great to inform me about
Not all of my assets are credited, because when I started this, I was stupid. So, if you see anything in here that's not credited in the readme, please inform me about it.
All criticism accepted and appreciated.
