[ch1998523]

Hello guys,
It seems that my ppsspp encounter some problems. I am playing pes 2013 and I am modifying the name of the players using osk. However, when I open the OSK, words cannot be shown so I hardly know what I have inputted. Anyone can help? Many thanks.

I am using the ppsspp in the openemu cuz I am a macbook user.

This looks like it's meant to be a message, not an OSK.

I don't know a lot about Openemu, but it seems like the assets files are missing.
