I bought the adapter from a japanese site thinking it was the one i needed. Thankfully i inquired here first, and was told it wont work.
So, if anyone needs this and has a spare adapter for use with Core Grafx(1) id be up for a trade. I can ship this anywhere in the world as long as the other person also is willing to.
If someone wants to buy it, ill sell it cheap. It looks to be in good condition and comes in a box (which says PAD-123 on it?) which is also in pretty good condition.
Send me a pm or reply to the thread, id prefer a trade for the adapter i need, if anyone wants to.
