On Linux every module resolves its references through one global scope,
and the guest modules are listed ahead of the host prx. When a title
bundles its own libc.prx, the host libc and the other host prx bound
their references to their own NIDs to the guest libc, so the host libc
built its standard streams on top of the guest _Stdout.
The exports of guest modules, and the guest and executable imports that
a guest module satisfies, now carry a #guest suffix. The title's imports
still reach the guest modules first, and a host prx only sees host
definitions, as on Windows. sceKernelDlsym also looks for the suffixed
name.
dlopen and sceKernelLoadStartModule passed the guest path to the host
loader, which cannot load the original ELF module. When a relinked module
<path>.guest.prx exists beside it, that module is loaded instead; for a
module the executable already loaded at startup the host loader returns
the same module. PPSA12544 loads /app0/Media/Modules/Il2CppUserAssemblies.prx
at startup and resolves IL2CPP functions through it.
