Pi 4 2GB + https://www.rgb-pi.com/ + the cheapest PVM you can find, + https://www.amazon.com/Omera-Adapter-Monitors%EF%BC%8CJVC-TM-H1750CG-TM-H1950CG/dp/B08JGCXKRT/ + some time spent tinkering = a setup that will make your friend jealous back.
I don't know where you're located but just get a normal PS1/PS2/PS3 SCART RGB capable cable of good quality, don't go for a cheap one and get a Female SCART to BNC cable and you're good, doesn't need to be off of amazon, buy it where you can, I have one and works flawlessly on every PVM I own.
