Motor City is kind of like Detroit, it's a automotive industry management sim, but it has a bit more detail.

Anyway, I keep getting an error whenever I run the game.

The soundhardware for VOICE uses a DMA channel that doesn't respond!
Please use IDMAS.EXE to correct the configuration-file!

I have the base, irq, and dma all set exactly the same as I have set in dosbox's conf file. Any ideas?

I assume that's debugging output from dosbox when running Motor City?

Hehe annoying little game it does some exentsive dma test with dma recording instead of normal playing, and then checks if the byte in the dma buffer has changed.

Sounds like overkill...

oh well somewhat hacked/fixed around it by faking soundblaster recording, seems to work somewhat now.
