An update: received the Game Boy back eventually, tested it immediately and of course it worked absolutely fine, with both games. So responded to the buyer to say that I've refunded them, but feel like you've wasted my time a bit. And got the following back:
'Why would i lie? It only played the mario game and not the other for gods sake what is wrong with people. If it was working fine i would have kept the item. Not everyone is a lier. I could have gone to ebay first and complained but i did not. I could say you have wasted my time but why should i.
kind regards'
Glad that's over to be quite honest. eBay at it's finest!
Maybe a zoomer that didn't know about the old blowing on the cartridge trick. It's plausible that he just saw the famous garbled Nintendo letters showing up and assumed it was broken
