Odd words on AceCombat X boot.bin

This is very funny. :D I was looking through the files on the AceCombat X UMD and discovered on the BOOT.BIN some words that aren't in the game (and arent appropriate for it either). It looks like a word filter, but I don't know when that would be needed...
check out the file from 0023bcc0 on a hex editor down.

Just looked...it does have some language in there.lol ...Maybe it won't allow you to enter those words as entry text in the game. BTW dude, this is a file from an actual UMD...doesn't that make this an illegal upload?
