FYI-
Here is what you do to get the hyperspin themes working. This is for individual themes, not the main menu themes. I'll touch on that later.
Step one, copy your hyperspin media folder to the AM layouts folder. Your media folder should have sub-folders of different systems in it like MAME, Atari 2600, etc...
Step two, configure display names to match the sub-folder system names, like MAME for example.
Step three, configure the display names to use the Media folder for the layouts. So for example, the MAME display will use the "Media" folder the layout. If you already have a MAME display created then just change the layout selection to use "Media". Basically, AM looks in the Media folder for a match to the display name.
Now, just rinse and repeat for other displays. Also, make sure you don't have any sub-folders folders in the theme folders, only zip files, as this might make AM crash.
