That actually sounds like a pretty handy tool, especially for someone like me who likes to keep backups of game updates or mess around with modded setups — kind of like how I use tools alongside Null's Brawl to explore different game versions. I've used similar scripts before, but fetchpkg really streamlines things with automatic merging, proxy support, and multi-platform compatibility. The fact that it works on both Linux and Windows is a big plus since I jump between both pretty often.
What really caught my eye is the jailbroken PS5 support. Being able to run it via an ELF loader and grab PKG files directly onto a USB makes managing updates a lot smoother. It reminds me of the convenience I get when running " Hileli Brawl Stars APK " on emulators — full control without jumping through too many hoops. I'll definitely be checking out Master-s' v1.0 release; it sounds like a solid step up from the original by Tornblom.
