Another little update/find on the Retro handheld that I came across: If you put in an OTG plug, like the ones used for the PlayStation Classic, into the port that charges it or is used for the 2nd player, it won't fully boot.... It will "turn on" but it get stuck and hangs like it's looking for instructions to continue booting. I'm wondering if file structure and/or file table, like does it want fat16 over fat32 or does it have it's own obscure filing system... I'm poking around a little to see if I get anymore response from it. Open to suggestions....
