The Professional Adventure Writing System is a Spectrum Adventure Writing utility. However, with the popularity of the SAM Adventure scene, a conversion utility was created by Martijn Groen to allow the utility to work for both 48K and 128K versions.
Although the games work in Mode 1 - the PAWS Extern command can be used to load in MODE 4 images, the full SAM Keyboard is used and there is even support for e-tracker music.
The utility does not include the Gilsoft PAWS A17C code base, which is required to work. However it does allow loading of this from disk or tape before it modifies the files.
