Would have been cool if there was a disc in the system
Yeah, that would be cool. A lot of people online are wanting them to try and get a PS1 game to run in it. But honestly, this thing was made in 1991, three full years before the PS1 was released to market (in Japan). I'm sure the processors inside this system are not the same as what ended up in the PS1.
It's a very cool piece of history that everyone knew about, but there was no real physical proof of until recently.
