Hey im in the process of forking the vita part of the game only and adding some QoL feature but while building the vpk i encountered a problem involving DrakonSound and i can't seem to find it anywhere could you point me to it if possible?

Hmm, I think it's just a renamed VitaSound, the dev of that was called DrakonPL here: https://github.com/DrakonPL/VitaSound
To be exact, the version that Dolmexica uses is this fork https://github.com/CaptainDreamcast/VitaSound/tree/Feature/LibraryConversion
On the Feature/LibraryConversion branch, which has some attempts from me to make some additional streaming stuff work I think.
Can't say exactly why I renamed it. I think the name change isn't even reflected in the forked repo.

Generally speaking I think compiling prism/Dolmexica manually is a bit of a frustrating struggle, my apologies. I have it planned to have a better way to handle these external libraries, but I can't seem to find the time for that recently unfortunately.
