Finally found an arcade that has KOF XIII in Taiwan. Been busy here, but found one in Kaohsiung Central Park area. It's a back to back cabinet, and one of the sides was broken and they won't have someone to fix it until Saturday and I'll be in another city by then. There was only 1 guy playing it who was actually decent.
I was able to do practice mode and found out that there's no button selection choice. Their layout was
ABC
D
Still not used to it, only got to play 2 practice modes worth. Will report further if I find competition or any other place that has it.
