I do know that it was at the time people when 3Ghz was considered asking a lot.
That was like 2008-2009. So bsnes was like in like 03x-04x versions.
I can't recall if it was before or after I tested Emerald Dragon, but it was pretty close. I remember it seemed bsnes was about the only emulator to run THAT game correctly. SNES9x had spotty SPC emulation which caused crashes on some versions, and I recall that was one of the games where you could HEAR the audio-barf in ZSNES' sound emulation.
