@retroB-0 I think that ScummVM needs an existing installation of the game to run it, not sure if it supports running from an installer iso/disc (where the files needed are not extracted by the installer and possibly packed/compressed).

Can you add more details about your setup, as requested in https://retropie.org.uk/forum/topic/3/read-this-first ?
What program did you install for i2c ? Or maybe you just enabled i2c through raspi-config ?

Can you post the complete verbose log on pastebin.com ?

@probottpric said in Retropie installing games:

So should i now create a new folder named psp ?

No, if the folder doesn't exist, it means that you didn't install a PSP emulator - use the RetroPie Setup entry in EmulationStation to install the ppsspp emulator and the folder should appear automatically.

Take a look at the PSP emulator page to see what are the supported game extensions and what emulators are available.
