In the game's files, in a folder called "300_MOVI", there is an FMV file titled ROCK.STR. It is unknown what this video's intended purpose was, but the answer may lie in the Japanese demo version of the game, in the demo's "MOVIE" folder. A video can be found called M_EAT.STR, and based on its name and appearance, it seems most likely it was to be used with Magic Earth Rune - in a similar way to Unite Magic (since they all play their FMV). The last changed date for the file is 1997. The last modified date for the rest of the game's FMVs is 1998, meaning M_EAT.STR was changed quite early in development, being the earliest of them all.

In other later releases like the PSP version, the ROCK.STR file can still be found in the game's data, though they similar go entirely unused.
