Indeed, 'tis a really bad idea to just come along and take something that isn't yours, especially if you then pretend that it's part of the original lineage.
In many ways, our communities are built upon fangames. We all make our own Asteroids, and Space Invaders, and QBerts, but at least we're vaguely imaginitive enough to turn them into "Rocks in Space!!" and "Invaders in Space!!" and "Obscurely diagonally placed floating squares in Space!!"
If you can pull of "DSision3", then you can pull of "Your Menu, how you like it, with your branding, get many peeps happy and a bit of publicity for yourself"
Otherwise, you might as well just ask Spinal to add the features, 'cos whatever you feel you've done, I guarantee you won't get any credit for it. EVERYONE will be thanking Spinal for DSision3.
For the record, anyone makes a JNKPlat game, and I'm coming after them with a big stick.
..
Make that a bigger stick.
