I don't game anymore but have kept all my consoles and games to see what can fuel my retirement funds
One of my favourite moments on the PS1 was accidentally discovering that if you turned the system on without a game and let it go into CD Player mode and put a game in, you can play the soundtrack to the game.
Also my PS1 was a very early run and didn't work properly. You had to flip the entire console upside down to get the laser to read the disc and function 'correctly'.
