I use PCSX2 to Emulate Playstation games on my PC.
I'm a PC gamer...and do not own any consoles. However I love the final fantasy series. (except for the ff13 which kinda sucked..but hopefully they will make good on their promises and rectify that mistake and return to the original style in the next version)
However When the Final Fantasy series went a Playstation exclusive in early 2000s (the last FF game for pc was FF8), I had to rely on emulators to play the subsequent ones on my PC.
Imho PCSX2 is the best Playstation/Playstation 2 emulator out there, with full quad-core and Video card support for emulation.
