do you need the actual cd to play games on ps emu?

well i was jsut wondering kinda new to this

Not really. There are big files called ISOs. Basically they're CD dumps/rips stored in your hard drive to use them with virtual CD-ROM devices like Daemon Tools. Also, you can make your own ISO from PlayStation CDs using a burning app.

Where to get ISOs? I won't tell. Read my sig to find out why.
