Yep, I've started on a Super Mario World hack, and it's probably harder than my other ones... All of World 1 has been changed, including the Yellow Switch Palace.

1-1:  Banzai Bills are much more abundant than they used to be.  Also, this level's filled with lots of tricky jumps... but also, lots of secrets are in this level...

1-2:  If you try to do this level first, you're in for a nasty surprise >:o) 
  Again, watch your step!

1-3:  From here on out, it's advised that you not walk blindly through any exit gate you see.  More tricky jumps here, as well as lots of Fuzzies and Bullet Bills.

1-4:  There aren't so many death-defying leaps here, but there are a few puzzles that may do you in you're caught unaware...

CASTLE #1:  Lots of Thwomps and Sparks here.  Thwomps aren't always evil, though...

YELLOW SWITCH PALACE:  This place is no longer drop-dead easy.  In fact, it's turned into a little puzzle you need to slove.

Have fun!

-Frank :o)
