I want to burn my (homemade) game to DVD for PS4 so I can give it to my friend
Ps4 games are on BluRay.
But, that won't work if it's not a cracked ps4. They have copy protection, etc., homemade games don't run on the ps4. You need a license to sign the games.
Also not via usb stick?
If the Playstation is cracked yes, otherwise not. Copy protection.
Is there another possibility?
No.
You need a license, and preferably a Sony dev kit.
Or just console with crack / jailbreak
I have the devkit from this video
No, this is not a dev kit, but an engine.
A dev kit is a kind of special ps4 for developing games. Costs a few thousand dollars.
What a shame
But it says ps4 sdk
Well, there's also a dev-kit as hardware.
You can also develop the game without a dev-kit, just in unity. Then you just don't know what the performance is like.
But, you need a license from Sony.
For xbox exactly like that?
Yes.

But publishing digitally is easier than on disk I think.
Seems like you get, if they take you, even a dev-kit for free with the xbox (no idea how it is with Sony).
