71)You must have patience if you want to make a good hack, because it can take months.
72)Don't copy names or stole ideas of other games and/or hacks; You must have... creativity
73)Snow/Ice Theme levels will be a bit more difficult, so try to use the Snow/Ice Theme (If you want to make one) in the 4th, 5th, 6th, 7th OW.
@Zuper Mario: This is easy! First, pass to the slippery area of Frosty Cave 5. You will enter in an area that isn't slippery. Look to this image:
When you reach this area, wait the lava go down, and... You can see a yellow pipe on the ceiling? Enter! And beat the level...
@Jility: First, find a Yoshi and a cape. In the level you will find a springboard, catch it. When you reach the end, drop the springboard after the Goal Point. Before the end you can see lots of throw blocks. Create a hole in the blocks. With the yoshi, eat a blue koopa and fly down of the Goal Point. When you are after the Goal Point, Yoshi isn't necessary. Catch the Springboard, and go to the real end of Koopa Woods 3. Enter in the last pipe, and use the springboard in order to get the key and the keyhole.
Finshed, I hope that you can read this, I'm not very good in English...
I saw on Wikipedia (Portuguese) a article of Super Mario World, and I saw a link to the Fusoya's Site, and downloaded Super Demo World TLC, and thought: How he did this? I returned to Fusoya's Site, and found Lunar Magic: A progam that can transform Super Mario World. I downloaded, and started hacking.
