Just downloaded the latest version of demul. I read and watched a few tutorials diligently. Managed to download all the bios and a couple of roms. Everything is placed in the proper folder and right paths. However, upon attempting to run dreamcast I receive this message "Error!(HRESULT=80070057) Failed to Create Depth Texture". Does anyone have any idea what I'm doing wrong or missing. I downloaded and installed Microsoft's directx software. I'm running windows 8 using a virtual machine(parallels) on a md 2011 mac. Thanks, I've been at this for the last 4 hours.
