Indeed. The purpose of adding those fonts was just to provide a temporary place holder.
Apparently, many games attempt to locate these files and give errors when they are not present. So, unfortunately, we do need to supply those files.
Those fonts were converted with the plain ttf2pgf application as a workaround.
However, I'm rewriting this application to provide full Unicode font conversion support and then I will replace the font files with their complete versions.
The regular Liberation Font files (ltnX.pgf files) should also be improved afterwards to match better the dimensions seen in the PSP.
