I've never pirated what you'd class as a current system and never would. I don't personally however have any moral obligations to emulating older stuff that there is no more money to (realistically) be made.
So I have a JXD7800 which has emulators for NES, SNES, GBA, Megadrive, Master System, NEO GEO etc. I don't feel bad about that in any way shape or form.
I also own a custom firmware PSP. However I only bought this second hand in the middle of last year, long after the PSP was dead and buried.
I bought everything when I had a PS2 and Gamecube. I bought everything when I had a 360. Like I said, I wouldn't pirate anything current, even if it was to become readily available on either the PS4 or Xbox One. But once a system is out of production and nothing is made for it anymore, then in my eyes, its fair game.
