--- Comment #13 from Stefan Dösinger stefandoesinger@gmx.at 2007-10-24 14:54:14 --- Correct, yes, the problem is that P8 is advertized, but doesn't work as expected.
In the long run P8 should be disabled, because it is emulated by unpacking to A8R8G8B8, so it is inefficient and slow. However, the emulation code should remain in, because some old DDraw games need it. I wanted to get the code working properly before disabling it(and thus, removing it from regular testing).
