The general rule of thumb with emulators (and this is an extreme oversimplification) is the hardware you want to run the emulator on needs to be at least 10x as powerful as the hardware you are emulating for it to run at full-speed.
Sometimes people have managed to optimize things so they ran...
only ps5 updated to latest firmware can go on psn, jailbroken ones just don't use psn or they risk getting flagged or banned, altho spouting profanity in online play alredy does that
