One of my dreams came true this year, which was playing F-Zero AX (the real arcade version) and Virtua Striker 4 Ver.2006.
Now I think only need Tekken 5 and Ridge Racer V, Arcade versions obviously. For you to have an idea, it was only recently that PCSX2 dev team, managed to fix the graphical bugs in the Console version. But i want to play the Arcade version and seems that Play! have bad performance on Arcade games even on an 13900k CPU.
