EBOOT.PBP packing was a POST_BUILD step with no dependency on the asset
pak, so an assets-only rebuild could silently leave a stale dusk.dsk
embedded. cmake/targets/psp.cmake now repacks EBOOT.PBP via a properly
tracked custom command depending on the executable, PARAM.SFO, and
dusk.dsk (and correctly embeds Dusk.prx rather than the raw ELF when
BUILD_PRX is on).
Separately, libzip's zip_source_filep_create (lazy seeked FILE* reads)
proved unreliable on real PSP hardware, corrupting reads of the embedded
PSAR (first EINVAL, then zlib data errors) even though the packaged data
was verified byte-perfect. assetInitPBP now reads the whole PSAR into
memory once and uses zip_source_buffer_create instead. Confirmed working
on real hardware.
