Thank you. I think the problem may be with PFS. I cannot seem to replicate the bug though (at least, I have no idea how to), although I do know that PFS is occasionally strange. Do you have some time to help me with confirming whether the issue is gone? I'm opening this to everybody (who do not mind wrecking some PFS partition), to try to speed up this testing process. I have tested my own changes to the PS2SDK and my __common partition wasn't wrecked, but PFS is a pretty complicated thing to deal with. Basically, you must create a new PFS partition and only use the fixed LaunchELF and HDDChecker on it. It can be named anything and you can do anything related to the fixed LaunchELF, with it. If you use other tools (which are bugged) to write data to the PFS partition, then the PFS partition may be damaged by them (we cannot prevent this).

It is a problem with FreeType and this 294MHz CPU. Using a different font might help if the font has support for hinting, which apparently the Google Noto font lacks.
