Quoted from Arcade:

Just got color DMD for Christmas.
But it refuses to load the USB code.
I have tried 4 different sticks
Reformatted 2 of them and double and triple checked the file name of colordmd.rom
After I hold the button down for 5 seconds the display goes black but no transfer of info takes place on any USB stick.
I can play the game fine in single color mode.
What gives?
I also saw to check for revision 1.3B but I can't find any revision number on my board other then A1.
Here is a photo of my install.
No idea why file won't transfer over.

Quoted from epthegeek:

That's a chroma board. Did you download the chroma.rom? Or Colordmd.rom old style?
Also check for extra suffixes like .rom.rom or .rom.txt
