Thanks for creating this, it's a huge time saver having it done with those magic command lines :)

I ported it to PowerShell and made it automatically get the DLC name from PSN server and also check the entitlements to make sure it's a DLC without exdata, you just put a list of content IDs into download_list.txt in the same folder and it will automatically create the PKGs with correct naming. (Right click it and hit Run With Powershell)
