PC ppd how to fullscreen?

Hi when i open the ppd emulator the window is quite small to me . is there any way to make it fullscreen or bigger?

(also i was reading on this mod named csinput , can anyone tell me what it does since i have a ps4 dualshock controller and its quite hard to play )

Run PPDConfig.exe, there you can change resolution or toggle Full Screen.
CSInput allows you to dualwield, for example you can press right arrow button on d-pad for cicrcles and up arrow on d-pad for triangles etc. However, your result won't be uploaded on server while using this MOD, since it's not really fair and right way to play PPD.
