Nicktoons Unite! (Nintendo DS)
Test Ambiance Sound
AMBIENT_GENERIC_TEST.SSAR and HUB_TEST.SSAR
Inside "/data/sound_archive_ambient.sdat" archive in the ROM in the SEQARC_AMBIENT_GENERIC.SSAR and SEQARC_HUB.SSAR files there is a test sequence under the name "AMBIENT_GENERIC_TEST" and "HUB_TEST".
Found in "/data/ui" is a file named splendid.tit. It's unknown what this does, but loading into Notepad++ it shows the names of some .pal files, possibly for color palettes on stages and screen, but I'm not sure about this.
