Mario vs The CC - The Penguin And Seal Mod

I made this in 2007, the reason why I'm releasing a video of it because maybe someone can help me fix it. The original game works fine, When I added the graphics the hack only runs for a little bit and freezes. When I tried to change the text and palettes, the game crashes & I don't know what to do. Well, enjoy the video and maybe one day this'll get fixed for a release...
