Based on the Super Crown power-up, most of the characters in this ROM Hack are in their transformed variation including Bowsette, Boom-Boom, and the Koopalings.
Also includes bonus patch file replacing Bowsette with Princess Bowser from the Mario Odyssey design. Which also changes to the W7 letter, boss sprites, and ending.
Included patches for both SMB3 USA and SMB3 USA Rev A versions.
Behind Pizza Time 64 this has to be the best ROM Hack in existance.
