d-fend reloaded is only a frontend for DOSBox, a DOS emulator.
Ace of the Deep is running very well with DOSBox because it is a DOS software, so it sure is running well with d-fend reloaded.
But unfortunately Command Aces of the Deep is a revised version of Aces of the Deep designed to run as a window software, not a DOS one.
So sadly it can't run with DOSBox (and so can't run with d-fend reloaded).
You can try some of the installation tip for Command Aces of the Deep and hope it works.

Or try to find a dos version of Aces of the Deep that unlike Command version has no problem running with DOSBox on modern OS
