Soon after the Genesis was launched in 1989, gamers everywhere made a startling discovery. It seemed that by removing certain titles without powering off the system, inserting another game and pressing restart, certain things happened. Some swap tricks merely changed the title screen to its Japanese equivalent while others opened the door to many famous cheat tricks. There was a serious risk of frying your console by performing any of these tricks (although I personally never heard of it happening) but curiosity is a wicked mistress and some of the effects were downright awesome.

Sega-16 has compiled what is believed to be a complete list of all these swap tricks, including the games used and the effect achieved. If there are any that are not listed here, please let us know and we’ll add them (provided they work!).

*WARNING!!*

Use these tricks at your own risk. Sega-16 will not be held responsible for any damage incurred to your system or software.

Tricks using Streets of Rage

Streets of Rage: Lots of Lives

Insert Streets of Rage into the Genesis. When the Sega logo appears, remove it without powering off the system. Re-insert it and press reset. In the options menu, the difficulty should read “6677.” This will give you upwards of fifteen lives per continue. It will also turn some of the game text to Japanese.

Tricks using Strider

Spider-Man vs. the Kingpin : Invincibility, Level Select, 60 Web Cartridges

Need some help getting past Venom and those other nasties? Hyru can help you! Insert Strider into the Genesis. When the purple logo appears in the background, remove it without powering off the system. Insert Spider-Man vs. the Kingpin and press reset. Go to the options menu. If the options are all “(!!!)” then you’ve performed the trick correctly. You’ll automatically begin with 60 web cartridges. If you run low, pause the game, press button A, and resume. For invincibility, pause the game and press buttons B and C at the same time. Resume and you’ll be invincible. This only lasts for a few seconds though. To skip levels, pause the game and hold all three buttons at the same time. You will skip a level every time the combination is pressed. The invincibility trick is especially helpful for beating the Kingpin himself, as his tendency to smack you against the wall takes off valuable time from the clock. With these tricks, saving Mary Jane should be an easy task.
