Super Mario Bros. is a platforming game for the Nintendo Entertainment System released in 1985. When Bowser invades the Mushroom Kingdom, it's up to Mario to stop him and save the Princess.

Castle in the Sky:
Journey through the mysterious world of Laputa in this hack and help Pazu to rescue Sheeta and the pirates from the evil hands of Muska. Based on the incredible animated movie, Castle in the Sky, this hack takes place entirely on the floating castle itself. You can run through the castle gardens, its walls, its massive forest, and the weaponized underbelly itself to defeat all of Muska's minions and save your friends. Almost every graphic has been changed to fit the Castle in the Sky aesthetic and incorporate its wide array of varied enemies. The world is counting on you, Pazu!

Version 1.0 - Ported Everything Over From Original Hack
(V1.0 of Co-Op hack is comparable with V1.2 of the original hack)


Known Limitations and Bugs:
- The Title Screen is "squished together" due to Supergamerguy's unfamiliarity with the Co-Op hack's code rearrangements, though he had previously been able to get everything the same as the original Castle in the Sky hack, except for the top right hand corner and the right side of the "Title box".

- In the original Co-Op hack by Corpse Grinder, Luigi's pallettes was edited to be tied to the pallette of the enemies, which holds true for this hack (since Supergamerguy's coding skills are almost nonexistent), so sadly, Patwo will not be colored like he was in the original Castle in the Sky hack, and is tied to the enemies' pallettes instead.

- Some of the enemies in their overworld states (namely Buzzy Beetles and Bullet Bills), are also tied to the Goomba's pallette, so they are now colored differently than the original Castle in the Sky hack.




If anybody with more SMB knowledge or better coding skills would like to fix these problems,
PLEASE feel free to do so! You can either send Supergamerguy the "update" through RHDN's Forum PM's
(and be assured that Supergamerguy will give proper crediting) or upload your own version on RHDN
(but please credit Supergamerguy as the original hacker).
