Flicker Filtering disabler
I don´t know if I´m the only person in the world who really hates the ultrablurry look of some xbox games which uses Xbox´s flicker and smooth filters to the maximum (for example, Wreckless and many others).
It seems sometime in Xbox hardware development somebody had the "wonderful" idea of making flicker filtering turned on by default, which blurs everything and makes some games to look sharper on the ps2 (even tought xbox games are rendered at greater resolutions), specially if you use RGB cables on both consoles
I mean SetFlickerFilter(); and SetSoftenFilter(); functions on the XDK.
First one lets you choose between 5 different levels of interlaced flicker filtering, and the second one activates a lowpass filter that blurries things even more.
You can see a clear example about what effects produces both settings at either UnleashX video options or XBMC gui/movie filter options.
Few Xbox developers use to set up its owns settings for flicker filtering, so their xbe´s just take the default flicker filter level (5, the maximum) and soften setting.
Ninja Gaiden and other Tecmo titles uses a less strong filter level (I think)
And games such as Wreckless the Yakuza Wars, uses the filtering and also the softening (in addition to rendering to a 320x240 texture and then oversample to 640x480

....Riddick´s also does this last one).
Many people hates interlace flickering, which is caused when the "image" in two consecutive lines from different fields have strong diferences (i.e. if you set one horizontal white line, and next to it a black line), so that´s because flicker filtering technices were created...but they had a bad side effect....blur...everything loses detail. Just try for example using Xebian, on a focus xbox (there is no flicker filter control for focus in Xbox linux yet)...you can get blind in a couple of hours. And of course games also look a lot worse than they could look on normal tv´s if they had flicker filtering turned off.
For me and (I guess) many other people is not a problem, and I prefer sharper and flickering image to blurry and not flickering image.
For example, I was absolutly amazed today when a friend of mine show me how Cold Fear looks on Ps2. Even tought it lacked of some advanced Xbox graphical effects (like height maps on the character´s model) everything else was ways sharper, and looked ultra focused in comparison with the Xbox version I was used to.
I´ve been searching long time for a way to disable it by patching the xbe´s itselfs and so, but I didnt have any luck. I even compiled a simple example with filter on and the same one with the filter off , but when I compared both there was lots of differences.
Would be possible to make something similar to IGR in order to turn off those filters?
Regards.
(of course flicker filtering have no effect in progressive resolutions)
