I agree with Jim. Have a look at the samples for particular concepts. Personally, I create an interface for my cameras and register the current camera as a service. This allows me to quickly switch between different cameras as well as get a reference to the world, view and projection matrices from any GameComponent.

Well, you're not really showing much here so people cant really get a good idea about the magnitude of your engine. Perhaps you can add some actual game/engine screenshots?

Content is always my biggest problem. However, there are a lot of free 'tabs' sites on the internet where you could get the [supposed] guitar notes and, as you say, spend long hours painstakingly trying to synchronise them to the music. The actual problem is around licensing the songs from the record labels - this alone is a ...

Good points there, Jim. The Input Reporter utility would be useful to map the specific controllers to their corresponding gamepad buttons. Now that I think about it, by rolling a couple of the existing samples into one, it would be fairly simple to make a GH clone.    

Well, Frets on Fire does quite a good job of using the keyboard as a guitar so it is possible. Besides, dont you think it would be nice to see some examples of using non-standard controllers? The GamePadType enumerator has more than just the standard GamePad in it. It would be great to see how to add 'Wheel' support to the Racing ...

I would advise updating to XNA 2.0. Using the project upgrade utility is quick and easy!

I have struggled with this problem for a while, too. I understand why the roll exists and that it is correct in its context. Jon: I just can't seem to figure out how to fit your compensation code into my camera though, and I cant find a complete camera class using quaternions that addresses the 'roll issue'. Could you take a few ...

Visual Studio really does have powerful debugging functionality that many people overlook. I must admit that I miss the advanced features of Professional Edition when working in Express. If you're working with a lot of data, such as lists or arrays, it may be easier to use Trace as Shawn mentioned. I've written about how to send Trace ...

The answer can be found on the page you mentioned, around three quarters of the way down. Color = tex2D( g_samSrcColor, Tex.xy);   Color += tex2D( g_samSrcColor, Tex.xy+0.001);   ...

The easiest way is to use the Intersects method of the Rectangle type. Rectangle playerRect = new Rectangle();   playerRect.X = (int)(sprite1.X);   playerRect.Y = (int)(sprite1.Y); ...
