yeah, in the 4 SE’s I’ve moded the PCB seems to be Identical to the Sanwa The Switches in fact were all the same across both sticks. The main difference between the 2 sticks is
-the circular cutouts that compromise the PCB’s rigidity, but that shouldn’t really matter
-The Plastic half circle peice that interfaces with the top of the stick is Black plastic (Instead of white on sanwa)
-and the restrictor plate is really, really stiff/rigid/harder to remove.
Other than that I think the sticks are identical. There might be a difference in spring, but I can’t really tell.
