Hello,
Another solution is to place a single cheat.db file in the folder:
R:\recalbox\system\configs\ppsspp\PSP\Cheats
(R: this is the letter of the usb key that I connect to my Rpi when connected to my computer)
The file can be found on the following github:
https://github.com/Saramagrean/CWCheat-Database-Plus-
(it's the same file described in the video above)
Then the approach in PPSSPP remains the same as described in the video
Enjoy
