So, I have issues with 3 games on Daphne. All load, but
Thayer's Quest
When the thing starts up and booting it shows weird things on screen like communication link failed. And it doesn't respond to keyboard commands so I basically can't insert coins or do anything.
GP Wolrd
Has lots of errors (including no sound) and eventually crashes
Cliffhanger
Simply shows a weird screen of 0s and blinking 1s

Any help is appreciated. Daphne forums haven't had posts in the last year so I didn't bother with that.
