Greetings! Since nobody made this layout here and (maybe) someone looking for a PSP layout. So, I made this layout myself for my psp emulator. And feel free to use it too! This works on any psp emulator such as PPSSPP, etc. I'll leave the instructions below.

First, download the layout here:
https://www.mediafire.com/folder/lc6h2412unvlz/PSP+LAYOUT+FOR+MONECT
After downloading it, open the monect app on your phone and go to the layout section and press the "+" icon in the top right corner then select "import from storage". And then find the .mlo layout in the folder where you put after you downloaded it.
The layout will then appear after importing it. If not, press the retry sign beside the + on the top right corner, or reopen your monect app in your phone and should be fine by now.
Connect your PHONE to your PC using the Monect app.
• Open the monect app both in your PC and your Phone.
• Connect your phone into your pc either using WiFi or Bluetooth or By cable.
(If you connect using cable then make sure to turn on USB Debugging on your phone).
• After successfully connected it, then it should be ready to go.
Open the psp emulator in pc (For me I am using PPSSPP pc emu) then go to settings>controls>control mapping. After that open the monect app in your phone and open then use the layout.
Map the controls by the corresponding buttons in the layout. And try testing it. And it should be ready to go.

Thanks me latur, have a good day!
