Whuhahaha!
Thanks to NoNameMame076u1 (which I've never had the pleasure of trying before), I got Tekken2 up and running.
Just like you said, Octo, there's no sound like in Zinc. But without DirectX enabled it runs between 18 and 40 FPS, which isn't bad considering. It runs at about 8 FPS with DirectX enabled. I think a little settings tweaking is in order...
I have a working Tekken2 PCB here, but I'm still in the process of getting my PCBs hooked up along-side my Mame PC. Still in the planning stage really.
