What are those cassette, Doha hiding in his bag?

I was wondering that too! I think the cassette tapes might be the ones bada was talking about getting rid of but I’m not too sure? It’s just a speculation I had

If u remember, in the beginning bada had to find the cassette tapes in order to save the game. He could only find them after the first death (correct me if im wrong) but doha had the tape in the prologue scene, before the game even started. This is hella suspicious bc how did he get a hold of it?

Oh and the other cassette is the one that bada said to get rid of (the one that blue hair put in the car) but doha already marked one, meaning he had that tape long beforehand (why? How?? We dont know yet)

You need the cassettes to save the gameplay so maybe he's doing it to sabotage the game cause he doesn't want it to end? Or maybe he doesn't want others to save any games and join them in the next run (like he want it just to be him and bada). But yeah I don't trust doha, like he kills too comfortably and he's just too shady.
