Apparently there's a really messed up Metal Slug ripoff in a pirate called 'Terrifying 9/11' with a full FMV of the twin towers getting hit (WTF). Very politically incorrect. But it even takes sprites from it. SNK was developing one for the GBC but then they canceled it to presumably work on the GBA version. Looks too good for an actual pirate game. This may be taking code from a prototype.

EDIT: Anyone have a copy of the ROM?
