Palette change mid frame

Changing palette entries in the middle of a frame on the NES is difficult, but marginally possible.

A few games are known to change palette entries for a status bar region:

• Fantastic Adventures of Dizzy
• Startropics

Indiana Jones and the Last Crusade changes its background colour many times across the title screen for a gradient sky effect:

• Annotated analysis of Indiana Jones
