Famicom Jump: Hero Retsuden

This page is rather stubbly and could use some expansion. Are you a bad enough dude to rescue this article?

Famicom Jump: Hero Retsuden is a Japan-only action RPG crossover game for the Famicom that's based on the comics featured in Weekly Shonen Jump. The game acts as a celebration to Jump's 20th anniversary at the time, and in total sold over a million copies upon release. Unfortunately the quality of the game doesn't match up to the hype and is generally regarded as a mediocre Famicom game in Japan.

An unofficial English fan translation would release in 2022.

Disabled Debug Features#

To do: Regarding the second code, the emulators I used always crashed after the first event switch. Also, apparently game over event 6 and events 2 and 4 are unused.

Use the following Game Genie codes to re-enable some disabled debug functions.

• PENNOYAA - While in the world map or in towns, pressing A on Controller 2 will refill your HP and B will add 65,535 money.
• PEXPVYAA - Enables a small event debug (Game Over and Teleport Display). Pressing Select during one of these events will switch it to the next one. There are seven events in total, but the game does not check for validity or wrap around to zero, so after the 8th event the game will crash.
• PEVAIPAA - Similar feature to the above, but for mini-games. Press A on Controller 2 to win the current game, B to exit it, and Select to switch to the next mini-game. The game does check for validity here, and will not crash.
• PAOEZZAA - A different debug routine for the last mini-game battle. Pressing A or B on Controller 2 will refill MP/HP, and pressing Select on Controller 1 will win the battle.
