Forcing 480p in games that don't support it

Is it possible to force 480p for any games that don't support it? Specifically I'd like to get Megaman 9 and 10 launching in progressive mode because my TV has a bad deinterlacer. I've heard that it can be done in some disc-based games like Madworld but I don't see any option for it in Gecko OS or in the gecko guide for gameconfig.txt .

Is there an app that can do this, or is it not possible without rewriting the rendering code for the game?

As far as I know, you can't do this.

Not without hardware. Not sure if you know about this [www.hdtvsupply.com]

Yeah, I've got the cables. It's a few games that will only work in 480i by design. Mad World, Megaman 9/10.

Sorry then I don't know :(
