This is the tileset I made for my game "Yet Another Mario Land". There is no color because that is how the data is encoded (color was applied in real time depending on the context). It is only 501 Bytes!
If you look at one of the textures, you'll find Petey Piranha, who is visible in-game. (Apparently, Yoshi starred in a play. You can learn a lot of things when you rip a game)
This one was a nightmare to rip, mostly because of the repetitive naming scheme. (Seriously, why does almost all the textures begin with "senior_course" and end with a number? And why is Daisy Circuit called "senior_course"?)
