Playable rating was missing which is the most common rating for PCSX2. There are some other issues like the images look bad for star rating and some other stuff. Also resize the compatibility table width a bit.
In reality it will show multiple flags like Korean flag but the flags aren't correct due to the structure in the GameDB actually being the languages more than the actual region.
At least people will have Korean flags and others for now and fix GameDB later as it's still a nightly/development cycle.
Though there are about 30 country flags included for future usage as of now.
