DC emulator won't boot Armada

[LegalFox]

I downloaded Armada from emuparadise and extracted the .cdi but both Demul and NullDC are trying to read it as an audio CD.

Selecting "Play Game" from the DC menu returns "Please insert game disc."

Both of these emulators are working with Sonic Adventure, but Armada isn't working.

Also, I downloaded the Armada .rar again - same exact file size and same error.

Sounds like it is not a Mil-CD aka selfbootable cdi image that both emulators need or a GDI image

http://www.epforums.org/showthread.php?85170 that is a Mil-CD and a better rip to boot

Thank you.

Demul is playing a strange saw-tooth sound whenever I descend to a planet. There are other sound issues as well. Do you know what is causing this?

Nope I just use my Dreamcast, it tends to work better
