I've purchased the Sega Flashback 2018 console with the SD slot and it recently began freezing on me. Funny part is that it happens at about 10 min of game time every time on every rom and most firmwares regardless whether custom or official. I say most firmwares as I'm not sure of how many there actually are out there. I opened it up to see if there's any shorts on the board but outside of a poor build quality, I saw nothing that would potentially make it freeze. I'd exchange it for a new one but I threw out the box as I did not expect it to be that poor of quality. If anyone could help or point me in the right direction, I'd greatly appreciate it. If anyone needs any pics of the internal boards or anything to diagnose the problem, I'll gladly supply them. Thanks in advance.
