I think as the PS2 is hard to emulate many different per game fixes need to be used via configs, so you need to link them with the specific game.
If you have an old fat PS3 with full PS2 hardware that needs no configs and you get the barely legible error you showed there is maybe something wrong with the device itself but as they were designed to overheat after regular use, there aren't many still around and you probably have a slim PS3.
Aldostools made a program to convert dumps of legally owned games to .enc and .pkg files where you can specify the correct config for each game, there is also a wiki page for it.
I recently read that the latest webman mod can also load the config on the fly for your inserted PS2 disc so that is easier than patching every game.
