Yes, this project uses assets from the original game. Jazz Jackrabbit 2 game files must be copied to
Source directory (symbolic link can be used too).
However, it's not required to use these assets. This engine is very flexible/modifiable, so custom assets can be used too.
Following versions of the original game can be used:
- Jazz Jackrabbit 2: Shareware Demo
- Jazz Jackrabbit 2 (v1.20/1.23)
- Jazz Jackrabbit 2: Holiday Hare '98
- Jazz Jackrabbit 2: The Secret Files
- Jazz Jackrabbit 2: Christmas Chronicles
To import all version into Jazz² Resurrection, it is recommended to copy the files to
Source in the order mentioned above and replace all files every time. In some The Secret Files releases, there is an extra
xmas1.j2l file that shouldn't be there and breaks The Christmas Chronicles. In this case, do not copy it to the folder or replace it with The Christmas Chronicles version.
The Secret Files Demo is not supported, only original Shareware Demo is. If you don't own any of these versions, you can buy Jazz Jackrabbit 2 Collection or you can try web version.
If you are not able to install/extract original files from GOG.com installer, you can use innoextract.
