The EMU8000->MPU-401 redirection is very limited under DOS as AWEUTIL can only work with real-mode stuff, not with late DOS-era games where you would expect/need it the most.
These later games use either the quasi-standard DOS4GW or their own proprietary extender (for example JEMM(?) in Strike Commander).
On the other hand, for older games, like DUNE 2, GM emulation works but sometimes it gets tricky... AWEUTIL should be loaded high to provide over 620k(!) free conventional RAM.

That explains a lot! Thank you for this. I've begun pulling some AWE64's out of some systems, especially those whose purpose is largely expressed by the forbidden conditions you've pointed out. Audician32's with the X2 or S1 is the replacement card.
