It keeps asking for me to Insert Disk B, even though it's been assigned through (Select Deathlord Scenario B Disk) the relorded menu.  I've also tried to manually override it by putting it in to Drive's 1 and 2.  Checked the config to make sure it was taking.  Not sure what else to try.  Any ideas?

I assume you’re using the latest version.

I will check if the scenario B disk is corrupt. Maybe that is the problem.

In version 1.0.7, both scenarios A and B seem to be correct. I've copied them inside the game (utilities menu) from the original masters, and the game validates both.
