Look into the ID3DXFONT interface (and ID3DXSPRITE)

Hardly a discussion if all you wanted was all the code to be fed to you, since you apparently didn't even bother to search for what I posted.

Have fun implementing your own routine, I guess.

Hook Direct3DCreate() API function if the game uses IDirect3D, for game using IDirectDraw you have to hook DirectDrawCreate() (check for hooking COM interfaces).
After getting the interface object you have full control over it.
Create overlay surface, get its device context and use GDI to draw text. Than display the overlay over the primary surface which you can get by enumerating or hooking CreateSurface() API function.

Another way is using proxy dll.

I have written described hook in delphi. But maybe if you a more specific question?

Yes, you are right with that iffy driver support. If I may ask what methodology would be more suitable for games using DirectDraw (old games)? Hooking Flip() or Blt() APIs and drawing text directly into the primary surface?

Hmm, I thought GDI and DD didn't get along too nicely, but I might have been thinking of something else.

I'm guessing the MSDN article for IDirectDrawSurface::Lock is saying that GetDC/ReleaseDC 'lock' the surface as well so you can do GDI drawing. I'm not sure how fast it would be though, but this is probably the easiest way.

If speed is a problem, I guess you could draw your character map into another surface and handle the drawing yourself.
