Karnov Forum  /  ROM header fix (bad graphics on second screen)
  rainwarriorrainwarrior

The Karnov ROM is commonly found with the wrong header on it. It should be mapper 206, not mapper 4. This IPS will fix it:

This should correct garbage graphics on the second screen of the game, on some emulators and Everdrive N8.

.

If you've got a PowerPak, though, you'll get an unsupported mapper error, so if you need to reverse this correction:
