Hidden Logo#
At the game over screen, hold Select + Right then press Start to see the publisher's logo screen.
This also acts as a continue code, as the game does not reset the level, score, or jewelry count after pressing Start on this screen.
Anti-Piracy#
- Upon starting a new game, the game performs a checksum on the CHR data.
- Upon reaching a new level, right before spawning the magic block, the game performs a checksum on most of the PRG data.
If either check fails, the game locks up.
Hidden Features#
If you hold Select while pressing A or B, the current piece will flip vertically rather than just shift the colors around, a nifty little trick that isn't mentioned anywhere. Further, since vertical flips aren't part of the Columns franchise, it's unlikely that most players would know it's possible.
