Do some games like Bubble Bobble, etc require it to be launched from disk-drive A?
Bubble Bobble launches fine on my Atari ST 520 as it only has an external drive (which is drive A) BUT it fails on my Atari 1040 STF when I launch it from external drive B.
I can make a A/B drive enable swap switch like I did for my Apple /// but want to confirm this is actually the issue first.
