Page up and down

Ok, have a s905w box and had to use a 4.6 test build on it due to the framebuffer issue,
Now that works perfect for the most part, only issue being that the page up and down to quickly scroll through rom list using L1 and R1 isn’t working,
I’m wondering is there anyway for reimplementing this by changing any of the configs, As with the build I have in an arcade cabinet it takes so long to move through it manually.

Have you tried L2 and R2? Perhaps you just mixed up the buttons when you configured your controller anew? Happened to me one time…

no l2 r2 on this setup, L1 and r1 set as leftshoulder and rightshoulder in es_input
