Hello, have you checked if this might be the source of your issue?

Plugin files are not interchangeable between ScummVM versions. You must copy all the plugin files
found in the /PSP/GAME/scummvm/plugin/ folder for every new version you install.
If ScummVM crashes on startup, delete the existing plugin files in the plugin directory
and copy the new ones again.

I tested both 2.7.0 and 2.7.1 on my real hardware PSP slim and they work fine.

It could be a problem due to PSP phat hardware having less RAM? I don’t have a phat model to test.

According to ccawley’s tests this might be due to loading from fonts.dat. In future versions, it might help to allow a smaller fonts-small.dat to reduce memory footprint on machines with less than 64MB RAM.

I believe this has been fixed in 0c317c7dc34548b5e9f8af247b9e199a952972d2 and should work with 2.9 releases.
