Hey there, Can anyone here recommend the best arcade joystick for TGM3 on the PC? I hear Hori is a reputable brand, but I'm not sure how well it plays with the TTX loader
Well, not "perfectly". Neither of those have a switchable 4/8 way restrictor on their joysticks. To play well, you really need a stick that has the option of switching the restrictor to 4-way to prevent accidental misdrops/mislocks. The Hori Real Arcade Pro series, Madcatz Fight Stick Tournament Edition, and any stick with a Sanwa JLF inside of it all satisfy this condition.
Yeah, EX2 and FS3 are only satisfactory if you're willing to do a $5 mod to replace the stock restrictor with a 4-/8-way switching gate from a JLF.
