First Contact/Unused

Rhythm Heaven Megamix
First Contact consists of the following versions in Rhythm Heaven Megamix:

Early Builds
In the Nintendo Direct 2015.4.2 build of Rhythm Heaven Megamix, the "Huh?" voice clip for when Translator Tom messes up a translation (which is reused from Ringside) is lower-pitched. In the final build, the pitch was raised make it sound closer to Translator Tom's voice.

Unused Content
There are unused sprites of some glasses.

There are two lines in Rhythm Tengoku: The Best+ used as a placeholder for the message. Each character in the correct message is displayed one at a time. An entirely separate set of messages for First Contact, likely an earlier version, exists in Rhythm Tengoku: The Best+ Taikenhan in the file "pajama.zlib/other_game.msbt". Most lines are the same as in the final version, but with spaces to artifiacially center the text. Empty fields in the table below indicate this string does not exist in the specified version. Note that in the game, each syllable is separated with "/", and the Martian's untranslated message is represented with a "0". The used strings, which are found in "pajama.zlib/ctr.msbt", have "ctrInterpreter" as the prefix rather than "interpreter".
