Harry Potter - artefact on LRPS2 / PCSX2

Two Harry Potter games give terrible errors on LRPS2/PCSX2 core

  • Harry Potter and the Chamber of Secrets
  • Harry Potter and the Prisoner of Azkaban

Is there any way to fix this?

On the Internet and on YouTube they say that you need to enable the “Frame Buffer Conversion” checkbox - and this removes black artifacts! BUT this is in the PCSX2 emulator

Is there any way to fix this in the LRPS2/PCSX2 core?

Found a description of the “Frame Buffer Conversion” function on a Russian website: https://hp-games.net/article-emulation-of-the-third-game-for-ps2-on-pc

Hi, try turning off ‘Force Texture LOD0’. This is one of those games that behaves badly when mipmapping is forcibly disabled.

setting software rendering in core options fixed these kind of issues for me.

Wow, thanks - yes, it helped! But in “software rendering” mode the playback stutters a bit

But the fact that the picture is normal is great! Thanks!

(“Force Texture LOD0” disable)

The problem with sound was solved by enabling:

Core options\Emulation\EE Cycle Skipping\ Maximum Underlock

Thank you all very much for your help! I hope this will be useful to someone else!
