Sanitarium doesn't work

[szczuru]

Sanitarium doesn't work on Vita. After launching just endless black screen. I can bring scummvm's pause menu and go back to launcher. Tested on 2.6.1 and 2.7.0. The same files works ok on pc.

Tested on GOG's version with and without polish translation.

The Vita Dev @rsn8887 is aware of that but if this problem persist also in 2.70 I think he could not solve it yet.

Yes, I still don’t know why this happens only on Vita. It works fine on other systems like Switch. Only the Vita has this problem, even though it uses the same graphics backend.

I did some debugging and found out that the videodecoder class returns current frame -1, indicating that no video track was found in the intro movie file. However, the file opening and loading succeeds. I need to do more debugging on Vita.

Oh, thanks! Looking forward for some more info.

I found a very strange thing which must be undefined behavior:

So somewhere, there is some memory corruption or something like that to cause this, but I have no clue where.

The good news is that this can be investigated on the emulator Vita2k, so no need for real hardware. But I don't know where to continue debugging this now.
