Make sure you save the complete disk, not just a single program from it. Once the tape is saved, [https://github.com/shred/tzxtools install tzxtools] to extract the last three files from them.

Make sure you save the complete disk, not just a single program from it. Once the tape is saved, [https://github.com/shred/tzxtools install tzxtools] you will need to extract three files:
 
* The title screen image, which should be renamed as "driller.zx.title" and has exactly 6912 bytes.
* The game data, which should be renamed as "driller.zx.data" and is around 37k bytes.
* The border image, which should be renamed as "driller.zx.border" and has exactly 6912 bytes.
For instance, for the original Incentive release (1987), you can inspect their files using the <code>tzxls</code> command:

For getting the files for playing the AtariST releases, the files should be copied from the disk. One way to do it is to dump the disk and then [https://github.com/jsummers/deark use deark to extract them]. There are two known releases: the original one (retail) and the Kixx release (budget).
