Were these two Game Boy launch titles, Tetris and Super Mario Land, ever available in the U.S. with the V1.0 ROM?
They are distinguished from the common versions by different music tracks: Tetris V1.0's "A Type" level song is "Minuet," whereas the same slot in the common (V1.1) version is "Korobeiniki."
Super Mario Land's death and goal tunes had no percussion track on the early copies (V1.0), but did on the common (V1.1) ones.
For all those of you who bought a GB brand new in August 1989, please put your thinking caps on.
