Ouch Ouch,
Its not your GPU, theres a couple of questions though first
Obviously does this occur ont he black screen, the wii menu channel ?
Does this occur just for SSBB or all games that you play on the wii?
GPU problems dont give you the benefit of noticing theres something wrong, they usually greet you with a big bad black screen or stop the system from booting all together
My two guess for your problem is (ER two of them)
1) Redo your downgrade, get all the IOS's from network not download to SD card,
---- Reason : Pal games/etc out of region use a different format of picture, not much but slightly different, for example, if youvve got a PAL iOs or something corrupt anything, problems....
Im going to assume your using the Orginal Disc (ill get to the back up later) so if you using this, Nintendo wii reads a NTSC U disc and forces the video to such. So if you are using an old disc / orginal disc some of the changes you might have made are the problem.
---- The first thing you need to do is try a different TV and change the video mode to see if you can duplicate the problem
2) ONce you've done the above (and I mean go again and do the above)m comment tell me more ,
I'd Honetly then say theres either again TV problem or Nintendo WIi wrong ios or problem.
However, if all this happens to be the worst,
then its your laser that reads the DVD, NOT the GPU
Unfortunately what always does the trick is to open the system and remount and clean it , via air duster / compressed air, you'd be suprised the amount of dust in the wiis.
Get back to me
And again
Discount everything youve gotten comments about, Boot2, burned discs, etc. This is not the same thing, and you dont need to bother with the answers above, do this first.
Your wii will thank you.
Thanks
Ill be here all week
Rhos
Tp better explain its not your GPU, try and think of the GPU as (Well it is) a computer Video card, its made by ATI after all, if I had problems in my screen it aint the video card on its last legs. There much more complicated than our old Nintendo/etc U/A/T video out coxial.
Well I wont get into more, just get back to me
Oh one more thing, I was upset bout Renee Walker in 24 dying, what a FEISTY red head. She was really cute, and 24 now killed her off, and no wonder its going under. Reiko Alysworth was Michelle Dessler , she was great.
And I cant help feeling attracted to Anna Gunn on Breaking Bad.
Yeah I thought I'd add that 2nd edit.
