This page is rather stubbly and could use some expansion. Are you a bad enough dude to rescue this article? Notes: According to FCEUX's code/data logger, over 30% of the ROM is unused. There are definitely more unused graphics, at the very least.

Jumpin' Kid is a Famicom adaptation of Jack and the Beanstalk.

Invincibility

Enter the Game Genie code PASVEZAA or change ROM address 0x1EA68 to 01, then press Up + Select on the title screen to make Jack immune to all damage. This will remain active until the console is reset.

Unused Graphics

Title screen and copyright info for an unreleased US version, titled (obviously) Jack the Giant Slayer. Unfortunately, it seems none of the tilemap data for this title screen exists, leaving just the graphics behind.

Above is a mockup of what the title screen might have looked like.
