Prince Yeh Rude

Prince Yeh Rude is an unlicensed Game Boy game released in the early 1990s. It is a block pushing puzzle game similar to Soukoban, but each level has a set of boxes with unique symbols on them that change every 5 levels, and unlike Soukoban, instead of pushing them into designated slots on the playfield, you have to push boxes with the same symbols into each other. It was originally released some time in the early 1990s, likely around 1993 or earlier, by an unknown publisher, and was a pack-in title for the Game Fighter, a DMG Game Boy clone. It would later be published again in 1993 by Gowin.
