Twenty years later, Street Fighter EX2 Plus is having a renaissance... Go figure. The EX series was tremendously popular in its day, by nature of the game being 3D- But EX2 came a little late and stood shoulder to shoulder with some serious competition. If you were around back then, you probably put your tokens into Tekken 3 instead.
With Playstation games slowly making their way to Fightcade, EX2+ is finally getting a second chance. It's electrifying! But for all the good DuckstationGGPO brings to the EX Series, there are differences. Remember these are still ports. The PS1 is not a Dreamcast: "Arcade Perfect" just isn't in the cards for EX2+ yet.
Street Fighter EX and its sequels ran on variants of Sony's ZN Board. EX and EX+ were on the ZN-1, while EX2 and EX2+ were on the ZN-2. Both of these boards are essentially suped up Playstations without CD Drives.
