PS4 Merger
PlayStation 4 uses .pkg files to package and distribute games and apps. These files are essentially a single archive containing everything needed to install and run the software.
The problem
Some of these files can be very large, making them difficult to download and transfer. I only had 32 GB flash drive and too slow cheap WI-FI router for remote game transferring
The solution
I made a PlayStation 4 app to merge pkgs on the console itself. It allows you to split large .pkg file into smaller parts, transfer them to the console using flash drive and then merge them together. The app was made with the free and open source OpenOrbis Toolchain SDK in C++ and anyone is free to use it.
