Over the past few weeks, I've been playing:
SNK VS. Capcom SVC Chaos: PCB version so it's a pain to swap out in the cab
KoF98: It's now a mainstay in my 4-slot
King of the Monsters: Meh
SSF2: played a few rounds of this at Arcade UFO in Austin
and finally...
Waku Waku 7: my new recent obsession is locating a copy of it for my cab. I was playing it on the Wii VC using a Tatsunoko vs Capcom fight stick but I couldn't change out the button configuration so I started using mame64 in Terminal along with WJoy to pair a Wii mote and fight stick. Feels better but still not nearly as good as a real MVS
