Working fine on my PlayStation 2 port which is based on the same old neogeo CD as your version... I would love to be able to help you, but unfortunately your emulator code is not open to the public, and you deleted all the comments I made I did it in your videos :/
Never deleted any comments youtube is doing that anytime words are said .. src code hardly any change from my github.. Does not work on the updated neoraine ether :) .. Not sure how that is working .. Seen your src i dont see anything to why that would make it work. Other then i use fully sh4 asm core for both.
