Apparently I'm on fire right now because I finally figured out how to properly deal with GC_ADPCM.
This script converts RIFX-headered gcadpcm streams to playable genh files.

Code:

# converts RIFX header files with GCADPCM stream to playable GENH
# written by AlphaTwentyThree of Zenhax
# script 1.01
# script for QuickBMS http://quickbms.aluigi.org

idstring "RIFX"
endian big
get RSIZE long
idstring "WAVEfmt "
get BSIZE long
savepos MYOFF
get CODEC short
if CODEC == 2
   set INTERLEAVE 8
else
   set INTERLEAVE 4
endif
get CH short
get FREQ long
get UNK long
get UNK short
get BITS short
get UNK longlong
get NOS long
savepos TEMP

set Wii_Area 0
for
   math MYOFF  = BSIZE
   goto MYOFF
   getDstring IDENT 4
   get BSIZE long
   savepos MYOFF
   if IDENT == "smpl"
      get NAME basename
      string NAME  = ".smpl"
      log NAME MYOFF BSIZE
   elif IDENT == "WiiH"
   set Wii_Area 1
      set OFF_COEFF1 MYOFF
      getDstring COEFF1 0x20
      getDstring DUMMY 0xe
      savepos OFF_COEFF2
      getDstring COEFF2 0x20
      getDstring DUMMY 0xe
   elif IDENT == "data"
      set OFFSET MYOFF
      set SIZE BSIZE
      break
   else # do nothing, just skip, e.g. JUNK
   endif
next
if Wii_Area == 0
   goto TEMP
   set OFF_COEFF1 TEMP
   getDstring COEFF1 0x20
   getDstring DUMMY 0xe
    savepos OFF_COEFF2
    getDstring COEFF2 0x20
    getDstring DUMMY 0xe

Just updated the script to support two other variants!
