HDLoader is a great little invention. There are some other programs out there that'll let you install a game from a PC over the network. Just put the game in the PC drive and it should load up on there. I'm pretty sure that I read it quite some time ago so I'm not 100% positive that it works. As for HDLoader on the PStwo - there should be a program that'll let you run an external USB hdd on there to get your games loaded quicker. Doesn't sound like it would work as well as the original HDLoader.
