He can't work with anyone else because it isn't his work. He took WildCard's work, maybe coded a flasher for it (which doesn't even take more than a minute) and is now taking credit for it.
The Scene has no respect for anyone and this is why you guys can't have all the cool things that have been created and discovered. The Developers that are truly capable of amazing things in the Scene have gone private thanks to attitudes like this and as a result, you will likely never see what the PSP is truly capable of.
Oh and, it doesn't matter if you give credit to WildCard or any individual Devs from said team who have gone public - you need their explicit permission to use their code. WildCard released the source code under the condition that NO ONE is permitted to take their work and use it - they are only permitted to learn from it.
You sicken me.
