Making Perspective 2D

I want to create a 2D breakout game using DX8, but i do not want the perspective matrix causing objects on the left or right parts of the screen to look smaller. Is there a way to create a perspective matrix that simulates using 2D graphics like in DX7. Go on an Intense Rampage

Can you explain more about this. How do I do it, and what does it do.

well... you can setup a orthogonal projection matrix in d3d8 by doing something like this:

D3DXMATRIX ProjectionMatrix;
D3DXMatrixOrthoLH(&ProjectionMatrix, WidthOfYourViewport, HeightOfYourViewport, 0.1f, 1.0f);
pD3DDevice->SetTransform(D3DTS_PROJECTION, &ProjectionMatrix);

and well... that''s all :=)
gluck!
