I watched a video where some poor old sod tried to replace the chip in this clone with a DNA 60 or 75. He took it all apart, talked way too long about his plan of action, and then ended the video before unsoldering a single wire and never uploaded anything about it ever again. The impression I got was he tried to make a video showing how easy it was to replace the board, only to find out that its actually a tedious pain in the ass. A bit off topic, but I think its funny.
