Just got my REVO in today, launched it and I am getting a white screen!!! It will not even turn on with a gba cartridge, which is not good! I have tried the reset button and still nothing. After some digging around it looks like you will need to upload the firmware yourself, which requires you to have a micro SD Card. If you go to the link (there is no virus, I scanned with BitDefender and Maleware Bytes) you can download the latest Firmware. Put it in the root directory of the Micro SD, it will load up just fine.
