@lupin it may well be a generic thing that would affect the official retropie image also but they are not supported here because we don't know what has changed under the hood, and also do not want to encourage the distribution of illegal material under the retropie name, etc. the image maker calling it 'official' is particularly egregious...
Actually you CAN emulate the PS2 on the Pi 4, but the speed is abysmal and the legwork required is insane. The tl;dr version of the story is you need to install Windows 10 using Windows on Raspberry and run PCSX2. SOME games run at playable speeds, but not many. Disgaea 1 and 2, Kingdom Hearts 1 and 2, Final Fantasy 10, and Final Fantasy 12 are playable. There are likely more, but those are the ones I've tested.
I changed it because I found emulation station running first was affecting the performance of the pi when doing normal desktop processes and it would quickly get annoying to have to exit emulation station and type startx to get to the desktop(for me let alone my son).
will go back to searching and see if i can figure something else out.
The underlying Linux operating system that RetroPie runs on top of is intrinsically multiuser.
You only need a free TeleTYpe program (I recomment putty for Windows) to gain access from your laptop in the same way as WinSCP does to move files.
Username pi - Password raspberry
The pi user does NOT have administrator rights, but the 'run as super user' keyword "sudo" can be used in front of any commands that needs them (no admin password required).
Make the terminal window as big as you need and use the nano editor to change configurations.
-Sega Rally - Ran great
-Kiss Psycho Cirus - Ran around in the first room but seemed to be fine!
-Puzzle Bobble 4 - Playable but with a bit of slow down (it seems so simple too...)
-Super Runabout - Seemed to be full speed but with intermittent stutter.
