v0.20 (05/24)
- Fixed issue #8 - add hi-score to show on menu screen.
- Fixed github issue #9 - hanging sound on endscreen. (i had forgot to set PSGStop(), fixed.)
- Fixed issue #10 - white border appearing on the text only screens. (set the correct pallete, column seems to be using sprite pallete color 0, since there are no sprites on screen, easy fix).
