RetroArch Dreamcast not an Associated Platform

[Dexll]

Trying to get Dreamcast working with RetroArch, but when I go to Manage Emulators, Dreamcast is not one of the Associated Platforms in RetroArch.  I imported the roms designating RetroArch as the emulator.  How do I get Sega Dreamcast to appear as an Associated Platform?

Add the platform name and pick the core from the dropdown menu.

Thanks!  Didn't see that blank field at the bottom, less know it was editable.  Added it, its not in alphabetic order.  Oh well.

You can sort it by clicking the column header you want to sort with.

Bam!!!  Son of a gun!  There we go.  Thanks!
