Praying the burned import disc boots up, probably.

Or he could have some clause in the contract that prevents him from bypassing the publisher for profit, or maybe he just doesn’t want the game to disappear and has a clause that lets him give away copies so he’s free and clear. It isn’t necessarily piracy. You asked how he could do this, I’m just spitballing possible answers.

I think he still owns the game. His publisher is the one delisting it.

My phone is a 2021 model and still has a 3.5mm jack and a memory card slot.
