Add more features please? Also, both characters dies at the entrance of the second castle.

There are some features I think is very essential to the game that is missing from this hack. The first one being Yoshi, although I suppose it's quite hard to implement him. The second one is the cape for player 2 which you disabled on purpose for some reason. The third one is the ability to use a powerup in a storage above, although that might not be to necessary.And finally running up those pink slopes. Also, have you attempted to fix Mario's garbled graphics when he's using the cape?

Yoshi will have to stay disabled :( I had to cannibalize the VRAM space he uses to be able to render the second player.

Flying with the cape is disabled because it doesn't make sense from a gameplay perspective. The screen can't scale like it can in NSMBWii so when only one player had a cape it would always just be them flying and the other person being dragged behind.

Triangle blocks are a priority, but a low one. They have similar ergonomic problems to the cape, but they aren't as game-breaking.

The castle is definitely a high priority. I don't know when I'll have time to look into this project again, but I'll leave it on my to-do list.
