RPCS3 Forums

The HDD that the emulator comes with is 300GB, but using the optional/mandatory installations eat that up pretty quickly, so I was wonder how to increase the size.

Cheers

RPCS3 doesn't limit the storage space it uses, if you mean the hard drive space that appears in the XMB then I believe that is some hardcoded value in the firmware that sets it to that
You can install as much as you want

oh, well that explains, cheers!
