Hacking [Help] HCA2WAV "Error reading HCA header" on all files

[OkazakiTheOtaku]

Hello,

I've begun datamining some PS Vita games. A lot of games pack their sound effects/music into a .awb file, which I have no trouble extracting with AWB_unpacker.exe. However, the resulting HCA files (in .bin format) seem unable to be converted to .wav (or anything else).

Any file that I try to feed into HCA2WAV.exe simply returns "Error reading HCA header"
I have tried files from Steins;Gate and Danganronpa.

I feel as if I am missing something very obvious. Please help!

Thanks!
