Technical
---------
The screen was squashed and had the wrong colours. This work was done:

After the loader has run, the game commences at 6700. This section is
where you choose what display type etc. To get the correct colours,
the code from 6723-6750 was shifted up to 6717 to make room for this code:

6747-6756: B4 0B BB 00 01 CD 10 B4 0B BB 01 00 CD 10 90 90
        -> First 7 bytes: select black/green/pink/yellow palette
           Next 7 bytes: select blue background, low intensity

To expand the screen, these bytes were changed:

7065 & 706D: EE -> 90
