Finally got the FG ripped. No sacrifice was needed, uses ExAnimated palettes. And it's compatible with this BG. Does contain another ExGFX file that also has the BG tiles. Read information.txt for details.
This foreground has very limited utility since it uses up nearly all available graphical space (with nothing remaining once coupled with its respective background), doesn't loop and doesn't cover a whole number of screens, which leaves the user with a massive cutoff to deal with. Additionally, but comparatively minor, it also doesn't cover the bottomost line on the screen.
You could've overwritten palette 0 instead of palette 4, which is preferred in this case, as shown in this diagram, found in the Submission Guidelines.
