This is the long-awaited sequel to JUMP. Started as a smaller collab inspired by the VIPs, it quickly spiralled out of control and became a true sequel.

Jump's storehouses and dragon coin reward system return, along with the level info menu, hint movies, and a retry system for the hardest levels. This hack also boasts a brand new ASM-heavy boss or two, new unlockable items, plenty of hidden puzzles and 3-UP moons, saving at any time on the overworld, and a few other neat features.

This hack restores the crosses that appeared in the background of stage 1 and on the zombie’s coffin from the Japanese version, and it also changes the names of Asutaroto to Astaroth and Sardius back to being called Samael once again as well.

It also makes it where you can access the hidden menu with the first controller by holding L and pressing Start as well. This hack also works with Lufia’s Super Arthur hack as well. The 0xED hex editor was used to change the name of the final boss.
