I re-attempted with just srep + lolz as per the advice of the forum user "Masquerade" and saw a significant (80mb) reduction in the final output, however decompression still failed, with the same error code (-1) as the first attempt given.

What srep are you using for decompression?

cls-srep, srepinside or srep.exe? Use cls-srep.

For the mp3 soundtrack, use a mask (arc.groups)

arc.groups file (next to arc.exe

$mp3
*.mp3

-msrep+lolz/$mp3=mpz

mpz is mpeg audio compressor.

Can confirm I'm using cls-srep, I'm honestly clueless as to what the cause of the issue is, but this seems to occur exclusively with Unity engine titles for me, with this and "112 Operator" both having issues with decompression. I resolved the latter by splitting the title into 2 archives (2nd archive contained .assets & .resource files which I identified as the files failing to decompress), which I hope may also help with this title. I'll have a look at mpz, as I assumed gains from it were similar, if not identical to that seen with msc, and as such have never tried it to compress mpeg audio. I'll test out my botched solution attempt and report back in a bit.
