Since the latest OpenOrbis PS4 Toolchain v0.5.2 revision last month and his PRX_505 Update, PlayStation 4 Scene developer @Backporter shared via Twitter an OOSDK port of @flatz's PS4 Remote PKG Installer (RPI) on his Github repository following yesterday's PKG_PFS_Tool Windows and MacOS updates.

NOTES
- Some functions are not in OOSDK yet (
) so i worked around this by manually importing them.
- Some freeBSD net functions where giving issue with printing debug info out, so i swapped these to the sceNet* versions as they seemed to work.
- if you have ran the original remote package installer it will cause a port conflict and this one will fail to function, restart your unit and only run this
- WINDOWS building only for the time being
