Yes I believe so...but before the jersey code came out for NHL'09 I had read on more than a few forums that people believed the code was used to unlock a playable version of '94. Although when the code was released and it in fact was not true, I was pretty disappointed. I still thought it was cool they had a '94 control style option however.
It's funny you mention that we talked Snes. About a few weeks after we recorded that podcast, Ben and I put some time into the Gens version. We both agreed that the audio did not compare to the Snes (as was the case with many Gens games) but the gameplay was much tighter...and that's where it counts.
Ps. It was actually the best games of 1993, I was so caught up in the '94 hysteria I lost my head for a second.
