no, you just need to make it region free.
so you’ll have to modify your motherboard in all region cases.
edit : damned, I didn’t see all previous replies.
I wasn't there since a while and I felt on this topic.
count me in $50 (for instance) to make this happen.
Even if it's not the main purpose of the topic : I suppose that porting CPS1 to CPS2 is the same hassle as what Darksoft described several times.
I'll spread the word about this topic.
And of course, as we decided together, Darksoft refund me for the spare part I bought to fix the board.
Even if the amount was negligible, I really appreciate.
