I have tried to multi mod using the Datel PCB and a PS1 official digital H pad and I have this problem where (PS3 controls) O and R2 are mapped the same as both buttons. When looking at it on PC, it says when I have it O pushed that buttons 3 and 8 are pressed. Same thing when I press R2. Then when I take out O off the button, R2 will still register as both buttons 3 and 8. However, when I have the R2 switch off and when I press O, it registers only as O as intended.
I have checked both circuits thoroughly and can’t find the problem as no solder or live points overlap and looking at the button layout on the PCB of Datel it seems that it can’t be that board because Triangle works perfectly fine.
However when I used this diagram, I didn’t solder onto where it shows R2 but instead right onto the bottom right point instead.
Any ideas on what the problem might be?
