A slight modificiation for the SID Plugin: A user can now provide their own C64 ROMs for better sound emulation.
This is essential on distros like Debian, where the Commodore 64 ROMs are not compiled into libsidplayfp because of copyright.
I do not want credit for these changes, the original SID plugin is the work of Ilya Kotov. I am unaffiliated with qmmp. This repo is for Qt5 qmmp (1.3.0+) only. However, the changes are simple to backport.

You must download the full qmmp source to build this. Just replace the same-named files in the qmmp source's "Input/sid" directory, and build the SID plugin with your preferred QMake targets.
Dependencies are unchanged from qmmp's. Use $ qmake -qt=qt5 to build, $ make, and then # make install once you've merged these files with the main qmmp source code. It should build and install exactly the same way, overwriting the old sid plugin.
