GameKids Advance

[Ninjinister]

Hello,
So I picked up a GameKids Advance, and I had no trouble getting the LCD contents to work. However, I can't get the NES stuff (even using the Famicom adapter) to show up on my TVs or Dazzle video capture device. I've got the EURO/US mains adapter and the device turns on with the little green light active, but nothing appears on the screens when plugged in via the component cables.

Is there something I might potentially be doing incorrectly?

Thanks!
