Thank you! I might be a bit busy this week, so I'll probably be able to take a more in depth look during the weekend.

About Pac-Man:
Interesting. A fixed alpha should be supplied, when padding is specified. Maybe there's a default padding value, if the alpha padding isn't specified?

About Minecraft:
Last I checked, Minecraft didn't display anything and just left hanging or crashed. It would be useful to have a game, that actually displays a RGB texture, so I could be sure, that it's decoded correctly, if I were to implement support for those.

But thats not all errors
Galaga legions DX use flipping which is not supported

Code:

{PPU Thread[0x1] (main_thread)[0x0023ac24]} Exception: Flipping is not yet supported.
(in file C:\rpcs3\rpcs3\Emu\SysCalls\Modules\cellPngDec.cpp:652, in function pngDecodeData)
