Cross Controller DLC: How to Play on RPCS3

Hi. So, I have LittleBigPlanet 2: Special Edition (And also Regular Edition but I always use Special Edition) on RPCS3. And I have the Cross Controller DLC on it. I also have a PS Vita, which is not modded and jailbreaked because I prefer not to Jailbreak. I tried connecting both devices for Cross Controller (On Vita I used the Cross Controller App located in PS3 Remote Play. On RPCS3, I pressed connect and there was instructions), but still stuck in step 1. I have the latest version btw. How do I play the Cross Controller DLC on LBP2 Special Edition? Yes I tried to follow the instructions but didn't work.
