There are 3 basic outcomes to using a VGA adapter with a current game system.
(the links are made-up screens which illustrate the result)
>> Possibility #1Conditions:
- GameCube Component Video Cable.
- Progressive scan compatible game.
- VGA adapter with Component Video inputs and supports incoming p.scan signals.
Results: The game looks the way it should. Resolution and framerate are intact.
>> Possibility #2Conditions:
- A game that isn't p.scan-compatible, OR you simply lack a GC Component Video Cable (using S-Video hookup instead, for example).
- VGA adapter *with* a [primitive] deinterlacing method.
Results: The VGA adapter takes the interlaced signal, poorly deinterlaces it by discarding one field, collapses the scan lines, then upscales it back to its original resolution. You're left with only half of the original vertical resolution, and 60fps games are cut down to 30fps.
>> Possibility #3
Conditions:
- Game isn't p.scan-compatible, or no component video cable.
- VGA adapter has *no* deinterlacing functions.
Results: Games show up as mess of interlaced scanlines, or NO PICTURE shows up at all -- i.e. not practical or not worth trying.
