Not to be too misleading, this is just another way to get progressive ~60FPS captures from a ~30FPS interlaced source. It does NOT involve dinterlacing. Much like the other method I came up with before, this method actuall acquires both odd and even lines of the original frame.

Well actually there are two methods, the second one would (possibly) work for any game you can pause. Both require machine assistance. The first one applies to CvS2. When the game is paused video keeps being sent but because nothing's moving you ge the perfect progressive frame as it lies in the PS2's video memory. So, what you do is you basically pause the game every frame, choose "Window off" from the training mode menu and you get the frame like that. The second way actually is simpler and you might as well do it this way since you're using some kind of tool anyway. Basically you pause the game and unpause it an odd number of frames later (depending how you count) meaning you get odd field of frame you're pausing, next set of fields contains part of the pause menu, wait another in-game frame, unpause and next field should contain the even lines of the pause frame. That "should" work. These methods, unlike the one I demo'd before, avoid having to record something twice, however now you have to write a pretty complex script to get only those frames you want. As the smileys sorta indicate, it's not exactly practical. I, for one, definitely can't do it, because I don't have the tools (p-pad) and I'm not sure if there's one that operates at a perfect speed (synched to the game's speed) to accomplish this.
