Hello everyone ! Right now, I'm trying to decode every music of Super Mario Galaxy 2, but I am having problems for some music! I will explain in detail all the many contents of the "AudioRes" that contains the music of the game. In "Stream", there is the music of galaxies, worlds, boss ... But it lacks the music, like "boss04", "boss09", "galaxy17" ... The music is in .ast, j 'I could convert them to .wav with VGStream. In "Waves", there are sound effects to .aw format I was able to decode through this method here: http://hcs64.com/mboard/forum.php?showthread=22046 After that, it gets complicated. In "SpkRes" there "SpkRes.arc". I managed to turn it into .rarc with szstools, but the problem is that inside SpkRes.arc extracts files, there are two files that I do not know how to open "spktable.bct" and "spkwave.csw" In "seqs" there "JaiSeq.arc". I .rarc and transforms the folder created by extracting the .rarc, there are 105 other .rarc and their files, not the extraires: rarcdump.exe the window opens, a folder is created but it is empty and the window never closes! In the "Info" folder, there are other .arc I converted .rarc and extract the contents: - ActionSound.arc: File "ActionSound.bcsv" ?? - BgmParam.arc: File "BgmParam.bcsv" ?? - JaiChord.arc: Many .CIT file ?? - JaiMe.arc: A "defaultme.bme" file and "metable.bmt" ?? - JaiRemixSeq.arc: File "defaultremixseq.brs" ?? - MultiBgmInfo.arc: File "MultiBgmInfo.bcsv" ?? - SoundIdToInstList.arc: File "SoundIdToInstList.bcsv" ?? - StageBgmInfo.arc: A "ScenarioBgmInfo.bcsv" file and "StageBgmInfo.bcsv" ?? My question is: How to decode, or even open files in .bct, .csw, .rarc file "SpkRes.arc" .bcsv, .CIT, .bme, .bmt and .brs? I used a wide range of tools, including szstools, vgstream, ripping_mama, BRSAR Unpack ... But I can not decode these strange files ... If anyone can enlighten me, thank you beforehand !!
