You can play multiple games on it, like Mario, Zelda, and many more. You control the characters with a special remote control that you hook up to the PlayStation. There are multiple other PlayStations by Sony as well. There are even games for girls on it. This is how you play the game of your choice: First, you insert the game CD-R and hook up the memory chip to your PlayStation, then hopefully, the CD will not be defective, and you press Menu, and press what you played last (if you saved your last game). Lastly, voila, you can play your game leisurely until your mom calls you off to dinner (hopefully not spinach).

2 - Shoppers note: "This was a first generation machine, the only model to have the RCA output jacks and the AKM AK 4309AVM 16-bit sigma-delta DAC chip. My son Harry has a third generation PS1, and SCPH-7501, which has the multi-pin A/V output only and a different DAC chip; I measured that sample, but it was very much worse in most respects than the SCPH-1001."
