Accessing the debug menu in 3rd strike (arcade)

I was playing 3rd strike on ggpo and I noticed someone went into a debug menu and set it to vs mode, so that you didn’t have to stick with the same character until you lost. I have no idea which option did this, does anyone know? For that matter maybe someone knows what all hte options do?

Press F2

Is there a translation of the menu somewhere?

Best thing you can do is set the DIP switch to USA so that the words in the F2 menu are in english. Memorize the options and then apply them on GGPO when you play with others online.
