That is right.the slot number has nothing to do with "speed advantage".
What's important is which IOS Base is installed in your Slot number.
if you install a cIOS based on IOS56 it will have "speed advantage" over a cIOS based on IOS57.
There's no reason to keep v8 if v10-alt work fine for you.
Either :
you replace slot249 and 250, and if 10-alt doesn't you re-install v8 in 249 and 250
or
You install v10-alt in different slot, if 10-alt doesn't work you don't need to reinstall v8 because you already have them.
I recommend to replace slot249 and 250, that way you only have the minimum IOS installed on your Wii (no need to install 40 different unneeded things).
The loader shouldn't automatically load IOS222 if you have IOS249 correctly installed (d2x v10-alt base 56 version21010)
I changed GX to always force the video mode to progressive, but it always display my MadWorld in 576i (I have the PAL game).
I finally tested CFG-Loader v70mod15, set the same settings as you and couldn't force the game in 480p (it always default to 576i).
Maybe the PAL game can't be forced to 480p at all.
I may need your help to fix the video mode patcher.
I'm using the NTSC version for exactly this reason ( 60 Hz, full screen )
Pal version of this particular game cannot be forced to 60 HZ, as this mode is also not present on the original disc.
Same is true for Scarface PAL.
Ntsc version of these game are superior in regards of video display and Frames per second.
Even these NTSC game cannot be forced to 480P in GX, is CFG loader they can be patched to 480P ( they normally resort to 480i, unpatched
I'll be glad to test for your, No problem.
