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 by Sandy or Prof. Knibble with the construction kit:
- Gittys Dreams I + II
- The Gitty's News (+)
- Knibble Girls I + II
- Frankys Horror Trip I + II
- Power Sisters
Unfortunately I couldn't find any working image of the "Giana Sisters Construction Kit" on the internet. Also some "Giana Sisters" clones were not available. So I transfered some of my old C64 disks to the PC these days.
All recovered games can be found in .d64 images in the corresponding folders.
The images are tested with VICE and Emu64 and seems to work fine.

To execute a POKE/SYS command, you have to load the game and perform a soft reset. Then type POKE … hit enter and the start the game with typing SYS 2127 and SYS 2098 respectively.
"The Power Sisters", "The Gitty's News" and "Knibble Girls II" couldn't be recovered from disc; so feel free to contribute these or any other clones.
"Franky Horror Trip 1" and "Power Sisters" couldn't be recovered from disc, but I found a disc image on the internet which I copied to this repository.
I'm not involved in any of these projects neither I own any copyrights for this software. Owners retain copyright to their respective works (Time Warp Productions, Rainbow Arts, Armin Gessert, Sandy, Prof. Knibble et al.). The disk images are contributed with no commercial intention. I just share the content of these over 15 years old discs to keep a piece of C64 sofware history.
