    Updated avatar, the previous one was outdated since September 2022.
  • Hacks
    Updated the package to again contain older milestone versions of the hack. I completely forgot to add them. The current version of the hack itself is the same, so no need to change version.
  • Translations
    Checksum of patched CDI has changed after fix done to initial 1.0 release shortly after submission.
  • Credits
    Previously mentioned TwistC as doing hardware testing before I discovered that testers aren't supposed to be listed here. However, the truth is that they actually designed the hack and decided which buttons should go where (which I then implemented).
  • Hacks
    Actually, the region lock is bypassed.

Super Mario Bros : Fourth Quest

Hack of Super Mario Bros.


Super Mario Bros : Fourth Quest takes on the idea of a ‘bonus quest’ after beating the first quest, introducing:

Instant Kill Dark Koopas, in all flying variants replacing Green Koopa who cannot be stomped and is immune to fire. Spiny Beetle from the inspired ROMhack “Super Mario Bros Third Quest” replacing buzzy beetle who cannot be stomped. Horizontal Podoboo replacing Bullet Bill who cannot be stomped.

The Velocities of the enemies have increased on average and the projectile frequency has also increased to make more difficult to beat.

The Hard Mode replaces all Goombas with Spiny Beetles with faster velocity. Sprites have been changed to be more red in general with no graphical edits other than the described above.

This will work alongside any Level or Music hacks, graphics hacks may cause some issues and no compatibility is garunteed.
