PSP port incorrect 4:3 aspect radio
|Reported by:||damsoftPL||Owned by:||rsn8887|
PSP ScummVM port has incorrect 4:3 aspect radio. Screen is actually displayed in 1:1 aspect radio even when "aspect ratio" option is chosen (I'm testing PSP ScummVM 1.9.0).
Below screenshot shows how aspect ratio works on current version of PSP port (upper image) and how it should work (lower image):

Fixed by the following commit:
Now the user has the choice on PSP between the old graphics mode "Keep Aspect Ratio," good for 16:10 games like Dreamweb, and a new mode "4:3 Aspect Ratio," good for 4:3 games like Full Throttle.
PSP development builds are currently crashing when loading any game. That is a different issue which will be fixed once a new buildbot is implemented. In the meantime, you can try out the change using the working development build here:

To make 4x3 aspect ratio work properly on PSP one minor change in source code needs to be applied.
I've already recompile ScummVM for PSP with that change and it works great.
The change is needed in backends\platform\psp\display_manager.cpp in the calculateScaleParams() method.
Below the original code and modified by me (I added one condition and one assignment)
