Vocaloid Mapping Contest 3 (osu!) - PARALLEL & SWAP round
The Vocaloid Mapping Contest (VMC) is back, continuing the mission to celebrate and promote VOCALOID, UTAU, and other vocal synth artists that deserve more love.
This time, mappers will team up to tackle songs from MARETU and mimizu across a unique three-phase format: PARALLEL, SWAP, and DUET. Simply pick any song from either of their Featured Artist listings and work with your partner to create the most impressive VOCALOID beatmaps possible!

Submission requirements
When submitting, combine all files into one .osz file. This means that you will have two audio files and two .osu files for the first submission (four .osu files for the second submission). Please ensure each difficulty includes the mapper's name, as well as the round it was submitted for. These will be anonymised before being provided to the judges.
To combine two audio files into one .osz, rename the first audio file to something else, then add the new file into the folder you plan to submit. Make sure to audio file references in the .osu files (marked by AudioFilename:) to the proper file names.
You can freely and resubmit resubmit your entry as much as needed until the timer below runs out. Please make sure only one team member submits.
Please contact a contest host well before the submission deadline (not afterwards) in case of issues.
