I haven't checked my TV, but the GamePad screen is black, and it's not turned off or dead.
I removed the sigpatch file, and put it back on and it booted aroma after I messed with some stuff in the HB Appstore..
I'm having a similar issue, whenever I put the sigpatch file on my SD, I can't load Aroma, it just has a black screen. When I remove it, it runs just fine. Any suggestions?
