I prefer to post here all the homemade controllers I found when I was thinking about doing mine. I've been working on a little (30x40cm) Future Tone controller since I really don't like the hori little one. I nearly forgot that I had to use all L1/L2 & R1/R2 for the twin slide (>> & <<). Take care with the drilling point, a sanwa 30/24/40mm is easy but big 100mm depends on their origin (original Sanwa or China cheap model). You can build a controller using a pcb of an old pad, I did mine on a Fighting commander 4 hori one. I will add pictures later (mine as well). All that pics can help you to build your own PjD controller.
