Awesome stuff Jone.
Excitebike is the first game I ever played with a map editor which still blows my mind on an 8 bit console.
Zelda LttP is the second to last Zelda game I was ever hardcore into, last being Link's Awakening, and is amazing. My favorite part of that sealed game is the little sealed hint book inside, itself sealed with little triforce gold sticker. That is quality.
