That has scrubbed up a treat, Blair - well done !
Send an email off to Ace regarding your issue with bootup. I've only ever used this board once and I can't recall the procedure to change the game, but Ace was VERY helpful with post sales support.
I have a feeling that the issues you are experiencing are because the game is using the Hulk code instead of Sinbad. Get the game booting as Sinbad before troubleshooting.
