If you’ve paid any attention to what I tend to expect out of the current crop of Vita releases, you probably know that game mods and translations are one of the things I love reporting on: the IA/VT translation and Taiko Drum Master translations along with the Modding of Isaac installer are things that bring us new stuff for the Vita, even stuff that was never intended for us. This newest release by developer MrComputerRevo fits into this last category since, in my honest opinion, breathes new life into a game that while very good, has a limit of enjoyability based on having less songs than something like a Project Diva game. Using his tools, you can add any song from the rhythm game osu! into your IA/VT! We’re not talking replacing songs either, we’re talking adding them into the existing line-up of songs so you can enjoy the best of both worlds – vanilla songs and mod songs!

What is IA/VT Colorful?

IA/VT Colorful is a vocaloid rhythm game – think SEGA’s Project Diva series – developed by Marvelous, which was only released in Japan. It plays mostly like how you would expect a Japanese vocaloid game to, except it was made to feature Vocaloid’s IA project. I tend to enjoy this game much more than I’ve ever enjoyed any Project Diva game so take that for what you will. Thanks to developer Nagato, we were able to start enjoying the game in English and now thanks to MrComputerRevo we can enjoy almost any song we want as long as it has an osu! beatmap.

Instructions for IA/VT Song Modding



HOW TO USE mod_tool:
1) Prepare your video and image files. The video has to include the audio track and preferably be 960×544 resolution. The image that will be used in the menu has to be in PNG format and 512×256 resolution. Additionally you can prepare separate menu audio preview file in WAVE format.
2) Launch IAVT_Mod_Tool. If it’s your first time launching please set the path to at9tool and Scaleform Converter. Also make sure you have x264 encoder named x264.exe and ffmpeg.exe in the “tools” directory.
3) Fill in all the fields. If you have already installed IA/VT mods before, check the “Download song_list_param.csv from FTP” checkbox and input your Vita IP address (make sure you have FTP running).
4) Press the convert button. After the conversion is done copy the contents of the specified folder to your Vita at ux0:/app/PCSG00355/ overwriting any files asked. This will give you a “clean” song. There will be no notes to press. In order to add that use osu converter.

HOW TO USE osu_converter:
1) Prepare .osu files of the beatmap you want.
2) Launch IAVT_osu_converter.exe from command line with parameters: osu_file.osu output.txt <offset>.
3) Rename the output file into “MXXX_DY_MID.txt” where XXX is the ID of the song (you can go to /outputfolder/resource/common/songs/ and see it there), Y – difficulty (1 – easy, 2 – medium, 3 – hard).
4) Place the output files in /outputfolder/resource/common/songs/ and transfer everything to Vita.

The first time you boot the game after this the mod song is going to show up as locked, you need to play some other song once to unlock it.

The developer has also included a video tutorial if you don’t feel like reading:
