pog! Just trying it out, can't hear what they're saying, but the game plays great. (I'm trying both 6581 and 8580 SIDs on Ultimamte 64 - but I'll try enabling one at a time and see if it improves it)
I tried it in Vice and it's clearer and louder than on both my real SIDs (6581 or 8580) it's just too garbled. You can listen on my vod from tonight if you like.
