The first obvious difference is the
SAMPLE VERSION label on the title screen. More importantly discovered by XKeeper the game has a demo that neither the Japanese nor the US versions have.
FMC Card Checker was provided by Nintendo to game shops that used the Nintendo Disk Writer system to verify that disks written are valid or not. Nintendo Disk Writer allowed shows to sell rewritable disks for only only 500, about $5 USD.
I’ve also seen the ROM named
FMC Disk Card Checker Ver 1.3 (Japan) (v1.2) (Developer Card).
