Seimitsu blue buttons, ArcEye3's and Remora in place
I had already replaced the original Sanwa buttons with blue translucent Seimitsu buttons. I also hooked up the ArcEye3's to the buttons and got the Remora board installed and working.
I think it was easier to start this mod the way I did it--replace the buttons and install the ArcEye3's and Remora board first. I think it would have been confusing and caused duplicate work to install the ChimpSMD first and then do the Remora and ArcEye3's, but it's not really a huge difference, I think.
