Since the formats the emulators support is already in the XML files, I would like to request that a simple list of supported file types is added to the SYSTEMS Page (Preferably under the Application selection, or Underneath the Roms Directory Selection but above the "Theme").
I suggest this as I ran into an issue where, upon scanning the rom directory, 0 files were found. In my case I was trying to use KEGA FUSION, with Sega CD CHD Files.
