I was thinking exactly about this.Working with limitations forces you to think out of the box, and hey, that's exactly how a lot of games we love we're made!Sometimes it's even entertaining to find other ways around such limitations
For example, the "wheel menu" in my theme shows these big buttons with rounded corners. They are infact transparent .png's in sourceflow. But instead of transparent color there's black in Wiiflow.
So I created a black gradient in the background, with the black color serving as a means to hide the black corners of the buttons.
It's not perfect, you can still see them when you return back to the Wheel menu from another location. But when you look at the wheel, you never notice the black corners around the buttons.
It also makes you wonder how much praise and love people like you and all the community deserves, it's rarely a easy job and yet people devote hours of their time and patience to it.
