I did a SMB3 8-bit Castle GFX. In this pack we have the original fortress tileset, BGOs, NPCs, SMB3 Mario 8-bit, and a Test Level inspired in world 6-third Fortress.
Note: There's some GFX that I didn't do but I put some like 8-bit Bowser, Dry Bones and Boo Buddies. I just put them to complete the pack. The credits are in the name of the GFX.
