Notes: Briefly considered ripping localised audio but all localisations amount to less than 100 MiB. Used a new patching approach that turned out to net a 34.64% reduction (from 1.53 GiB). This involved building the oldPath post-install, rather than ripping one of the audio formats, for separate processing, from an existing oldPath and patching it post-install. A handful of the "*.wav" and ".ogg" audio don't play well with their respective compressor, so (like with many titles), validation tests will be required. I unfortunately didn't save the checksums for the offending files, as this particular title has been scattered across different drives for a handful of weeks now (due to unsatisfactory initial results), but thankfully given the size of the title, the validation tests don't take long.

I'm unsure of room for further gains, the patch file is a close to perfectly optimised as I can currently manage, but if there is room by processing individual asset types separately, I'm not currently aware of them.
