You're right. Here it is again.
For others: there is now an option to rotate the shadow mask patterns. This is (only) useful when you display vertical games in MAME on a standard landscape orientation LCD.
There are two shaders in this archive. The only difference is that the "VERT" version rotates the shadow mask by default. The idea here is that you use the VERT version in a "vertical.ini" so that it gets used for vertical games only.
