Played through all of the games once just to check the emulation. SF1 is still unplayable garbage. Super Turbo's AI is still fucking ridiculous on the US version. Vanilla SF3 is still ugly and baaaaaaad. The input lag playing on an LCD TV was killing me on V-ism combos but weirdly not for parries. Gonna need to plug my PS4 in to a low-latency monitor if I wanna play online at all.
Options are barebones but 12 arcade ports with 4 online supported games is still decent for $40 retail. If I wasn't such a sucker, this would be perfect when it eventually goes down to $15/$20. Of course, no one will be playing it then.
Edit: If you mean regular Super SF2, it's still slow as molasses and completely unnecessary once you play Super Turbo unless you REALLY like the Zangief magic SPD glitch or something.
If you meant ST, it seems good. I haven't really had a chance to dig in to it yet but most of that game's quirks seem to be there (weird damage output, the aforementioned ridiculous AI difficulty, Old characters and Akuma). The speed felt a little off to me but that could just be because I played it immediately after player regular Super so my equilibrium might've just been off.
