Curved screen shader
Looking at the script more thoroughly it takes the first writeable path from $XDG_DATA_DIRS which may or may not match with the install prefix. I've worked around the issue with: XDG_DATA_DIRS="/usr/share" make install
I get the icons installed in the wrong place when specifying --prefix=/usr On one system they end up in /usr/local and on another in a yet different path. I seems that the xdg-icon-resource script uses some semi-random path extracted from $XDG_DATA_DIRS: https://gitlab.freedesktop.org/xdg/xdg-utils/-/blob/master/scripts/xdg-icon-resource.in#L222 Either I'm missing something or it is completely unreliable, the docs aren't helpful though.
Cool! I have some (mostly build system) fixes in my fork here: https://github.com/drfiemost/porg/commits/master/
Released libsidplayfp-2.16.0
In any case, however, Leandros repo is the place to report this, thats where the development happens. resid is planned for removal in next major version, residfp is mature enough to supersede it. Anyway, the parameter is configurable exactly for this reason, if you don't like how it sound just change it. Maybe if there are enough people preferring a different value or someone with a solid proof the default can be updated. Also check NTSC tunes, the 8580 filter depends on CPU clock.
