Kreee is the mod genius, however:
IMO you'll struggle with that mod.
no 3rd party teams have got around the PS4s security time out at the moment.
so you'd need a pad hack or similar to get it to PS4, then a similar for the xbox 1.
it wouldn't be neat or cheap.
Other options:
1/ Buy a CronusMax converter and put up with having to reset it every 8mins for PS4. all the other formats work fine.
2/ get a PS360+ board which will replace your current PS3 one and do the same as above but may require some soldering, but give you other older platforms as well.
3/ grab a Venom PS4 stick as a spare, fairly cheap @ £60/£70ish.
