Hi guys, I have been using a Raspberry Pi with Retropie for my emulation for ages. It's used for games up to PS1 and it's fine, but I wanted to upgrade my emulation to play games up to PS3/360. For that I think I need to use a PC right? What's the recommended spec for that use case?

It's gonna be used specifically for emulation hooked up on a TV on my basement and with Retrobat or some system like that

I appreciate your inputs.
