KA Archive - vanjac/zoomscape-info GitHub Wiki

Data for ZoomScape games is stored in KA Archive files. These have various extensions but all have the same format. The files can be extracted with QuickBMS using the Knowledge Adventure BMS script, or by using my kaarchive.py script.

KA Archives are simple directories of files and ZoomScape treats them as such (even allowing paths to nested files). Their extensions label the type of data inside, but this isn't enforced.

Extensions
