I was trying to make a MVS with Neogeo X case but the MVS-1C board is working with Samurai spirits 2 only. (Other games like Samurai Spirits 5 or others are not working)
I was looking for the cut line on board but I cannot find it.. (I made it with another board cause it is not a big problem but I just want to make this board works also. )
This is the one I made. It is Korean but there are lots of pictures cause I hope you can understand.
