I already set up others flash cart without problems. I installed the lastest kernel and the firmware, but after i boot the menu and try to boot any game (trimmed or not) all i get is a white screen. However i can load any homebrew whitout problems like moonshel or comicDS.
Is there any other file that i need to copy? Do i miss something to get the card working?
Here are pic from the files in the micro SD, the second are the file inside the rpg folder

I'm not all that knowledgeable but I had a similar problem but I fixed it when I downloaded the firmware and stuff from here http://r4i-gold.com/en/download/ and just put it into the micro sd card

but I am having a problem where the games freeze randomly, so be wary if this works for you
