speaking of Hu card convertors, does anyone have one of these for sale? i
already own a Core Grafx, but i lack the CD attachment, as well as the
overbloated funds to purchase one. i basically need to convert a Japanese
Arcade Card Pro or Super System 3.0 card to work with my US TG+CD combo. are
any convertors specifically UNreliable for this, that i should steer clear
from? Ebay seems kinda steep these days, so what's a fair price? or perhaps
someone knows of a site that still sells them? thanks for any help, gang!
