Around late 2017, I believe. Not with a computer, but with a PS3 I had gotten that I put some custom firmware on as it was one of the later fat models that ditched full backwards compatibility with physical PS2 discs. Later on I moved on to DraStic on my phone, realized I could play GBA on my PS3, hacked a Wii, got a computer so PPSSPP became a go-to, lost the Wii, got a BETTER computer so I can actually emulate PS2 decently, got a new Wii and hacked that one.
Still got the PS3 too. It needs a cleanin' something fierce but it still works.
Oh right, I learned about emulation in general from my uncle. He's got a ton of modded consoles and a lot of discs. Fond memory was tryin' out one of his modded og Xbox's.
