I’m guessing this is the original Street Fighter EX2, where Excel attacks needed to be chained (rather than EX2+ where you could just mash the same attack button multiple times during Excel).

Actually this is vanilla SFEX2, released only at arcades. SFEX2 Plus (the version that you mean) got ported to PSX with some character voice clips replaced with new ones.
