For anyone having issues with ORP after updating to PS3 Firmware 2.8 here is a temporary fix until Dashhacker updates the app again, to quote:
Sony has changed Remote Play as of 2.80 to require the client's MAC address to match that of the registered PSP's MAC address. We're still working on a proper solution for this, but in the mean-time you can spoof your PSP's MAC address to get local connections working again.
In Linux, this would look something like (change aa:bb:cc:dd:ee:ff to your PSP's MAC address):
Code:
# ifconfig wlan0 hw ether aa:bb:cc:dd:ee:ff
For OSX, this works similar:
Code:
# sudo ifconfig en0 lladdr aa:bb:cc:dd:ee:ff
The above doesn't work with the AirPort (interface en1); so you gotta be wired.
