Giana Sisters "The lost Levels"

In 1989 the two german programmers Sandy and Prof. Knibble hacked the C64 game "The Great Giana Sisters".

They programmed a Giana Sisters Construction Kit which made custom level building possible. Unfortunately they could not officially release the software due to copyright and legal issues. Until today there is no "level packager" to build a executable game of the construction kit generated levels but you can use the construction kit to build seperate levels just for fun.

The following "Giana Sisters" are created with the construction kit:

  • Gittys Dreams I
  • Gittys Dreams II
  • The Gitty's News +
  • Knibble Girls I
  • Frankys Horror Trip I


Unfortunately I couldn't find any working image of the "Giana Sisters Construction Kit" on the internet. Also some "Giana Sisters" clones are not available. So I transfered some of my old C64 disks to the PC these days.

Cheats and start options

  • Press A+R+M+N to skip current level
  • POKE 5083, 5 (no giana movement animation)
  • POKE 8207, 173 (extras stay after loosing a life)
  • POKE 4242, 42 (alternate jump)
  • POKE 6664, 96 (bridges indestructible)
  • POKE 2213, 164 (giana is always in punk mode)
  • POKE 7450, 95 (unlimited time)
  • POKE 7236, 27 (no collision check)
  • POKE 7326, 173 (unlimited diamonds)
  • POKE 2446, 255 (unlimited lives)
  • SYS 2127 (start without highscore load)
  • SYS 2098 (start with highscore load)

To execute a POKE/SYS command, you have to load the game and do a soft reset. Then type POKE … hit enter and the start the game with typing SYS 2127.
