Black screen usb

Hi I am fairly new to the scene, I was originally on bios 3.x and it has been updated to 4.2 before I tried any of this. I followed a guide to install homebrew channel and cIOS249 v14 but when I loaded a game from a mem stick I got a black screen. So I then followed the following guide
http://www.wiihacks.com/recommended-...d-any-wii.html
which has downgraded me to 4.1e and I still get the black screen I have tried two memory sticks and a random usb HDD. Mario Kart gets the warning up about swinging your controller but and then a black screen, super mario bros and mario galaxy 2 both go straight to a black screen. My main memory stick is a 8gb kingston data travaler which is listed as compatible. In the usb loader I have tried ios 249 and 222 to load the games but still the same.
Here is a copy of my sys check:

I have also now tried burning the mario kart game to disk and using neogamma it does exactly the same, ie loads the warning screen and then just black screens.

sounds like it could be a bad dump
try redumping the game and trying again,

you also need to post an intro in the introductions forum
and if you want to add more information, there's an edit button you can use

hi thanks for the reply i have been to the intro area now :) is there a way of verifying a dump?
or should i try taking another backup? an observation i had was that my my ios36 has a rev 54321 which seems different to what evryone else has on the syscheck help page, could this be a problem?

Im not sure how to check a dump
try making another one and see if that works

ios36 should be rev3351...

Any ideas how to get it yo the correct revision with out bricking my wii

You have the custom IOS36 from Mauifrog's guide just leave it as is.

Explanation:

It's just a patched IOS36 with the version @54321 so an accidental update won't wipe it out. :)

didn't know that Mauifrog's guide did that - now I know
I'm guessing so it's never updated

@OP I'm guessing you have a bad dump of the games you're trying to load. The only factors when using a loader are: the dump, HDD, cIOS249 for most games or cIOS222, 223 for a few other games.

Also, very few games do have certain fixes such as loading an alt.dol, etc. You can find those fixes by searching the forum.

thanks for all the useful advice i will do some more testing and let you know how i get on :)
