If I read things correctly, the picture is formed inside the video memory as a 480p or 525p image but is usually sent out to the AV plug as a 480i or 525i image. So, technically, all games are progressive scan but that images are "dumbed down" to interlaced for standard video after formation. So there shouldn't be any slowdown when progessive scan is activated by the Xploder product.
There are some games that will blow up when using this product but it appears to be about 5% at the moment.
I've also been informed that the Blaze VGA product, which I mentioned earlier as using algorythms, did somethihing similar to the Xploder product. However, the Xploder product is supposed to be a lot better than the Blaze unit.
Now what I need to do is find a solid way to remove sync from green so I can make a decent VGA adapter for my PS2. My MultiSync 3D can do sync-on-green but this will give me an excuse to do research on sync removal (which is much harder than sync separation).
