Ok, seriously guys, drop that legal BS. I'm all for playing PS2 titles on PS4, I even bought San Andreas for 15 bucks. But who cares about someone getting a BIOS for the PS2? I bet even Sony doesn't mind. It's neglible, even if illegal on paper. I play SNES and GBA games on my PSP all day and I don't give two fucks about it. It's technically illegal, even though I do own the original games, but I still may not download them from the internet. But I couldn't care less. I want to play those games on the go!
Just let the people play on whatever platform they prefer. I don't have problems with people prefering PC with emulators, but I personally like it on Ps4 more.
Aye, it's just some people are probably reacting to the very first line of the OP.
Fancy hearing me on an amateur podcast with friends gushing over one of my favourite games? https://youtu.be/1I7JfMMxhf8
