I did recall Hello made a SMB2 engine. Which is glitchy and choppy like his SMB engine. So I decided to leave my SMW engine due to the coding and physics are horrible, and started this:

Supernova Mario Bros. 2 Engine (Saturn Mario Engine 4)
Platform: Game Maker 8.0 (Pro)

Which features (Planned):

• Generic SMB2 pull-n-throw system
  
• Some additions from Super Mario Advance (GBA)
  
• Jump-through slopes
  
• Character selection system
  
• Organized coding (Easy to switch key options and global functions uses an object called obj_SYSTEM instead of global.[function] which reduce system memory usage) [Thanks to DarkBlueYoshi and Kremling]
  
• More to be planned.

I made this for your engine.

If you need anything ripped, I can help.

Mega update!
