Hook some funcs in Me and My Katamari.

One is a very hardcoded screenshot download / vfpu convert to 565, and the
other is some very weird check to make sure render is clear or has
happened or something.

The screenshot func detects downloads for the "Royal Album".  The render
check detects downloads for post-rename (no idea why it checks here.)

Fixes #7695.
