BTW, HS, as I suggested in the other thread... KillAGA and JST may also be worth a try if you're not getting satisfactory results. I'm pretty sure WHDLoad isn't the answer to EVERY game out there (obviously it is if the game is NDOS and no JST loader exists for it, but you know what I mean!).
I should also point you out to Dr Zarkov's still-active webpage
and the various HD loaders there. I don't know how much friendlier they'd be on a CD≥≤, but I thought I'd help out somehow!
