Hello Friend.
I realized something that made me a bit frustrated about ppsspp in version 5.16 (I am currently at 5.15 again)
I realized that until version 5.15 the ppsspp had better image quality, the setup screens were set to common size and the image was good ...
however, from 5.16 when I access the configuration screens, the size of the letters is enormous, some jump off the edge, not being seen, it is as if there was a large zoom applied throughout the emulator and this also influences the graphic quality of the games that ended up becoming more serrated and worse than what we found in 5.15 ...
the platform I tested was in RPi 3, I'm in touch with AirHead as well, but I wonder if it would be possible to return the ppsspp to the normal resolution or zoom as it was in 5.15 in an upcoming release (5.17 maybe ...)
