Hello! Been playing this game a lot lately and I've been thinking about running it. However, I play the game using the Capcom Arcade Stadium collection on Steam. Would this count as PC, Arcade (EMU), or something else?

Arcade Emulation I guess

Hello, if runs are done using Capcom Arcade Stadium through Steam, then it's officially considered PC as platform. (USA/JP/EURO).

Good to know, thank you!
