Fix for audio corruption for DOA3 emulated in CXBX-R:
Edit2: reverted the fix. It was rushed. Somehow a file still remained corrupted with that fix.
Python:
#-------------------------------------------------------------------------------
# no more corrupted sound in doa3 in CXBX-R emulator
# will fix doa3 wva loop_start in 'loadfile.afs' to the nearest sound chunk begining
#-------------------------------------------------------------------------------
