Uncanny over at the Spanish GP32 forums has discovered his Dingoo is different inside than mine. The main difference appears to be a single 4GB NAND chip, and faster RAM chips @ 166mhz, not 133mhz. Uncanny has also provided an educated guess as to the hardware details of the Dingoo’s acreen, and provided a link to internal pictures of his Dingoo at the bottom of his post
