Problem with AR GC

Here is my problem (I THINK the section is right...):
It seems that my AR disk only works with Zelda: The wind waker.
It load fine, I select the codes, "open the lid" and put the game in. It then go to black screen for 15 seconds, like there is no video input, I hear a sound and then the video is back on, and the game play with the active codes.
Problem is it's only work with Z:WW.
If I try it with Eternal Darkness, or Baten Kaitos, or StarFox Adventures it goes on black screen and stop there.
The strange thing is that It worked before (I used a code in Baten Kaitos to pass the flying ship...).

I'm on 4.2E, with mios 4, bootmii, component cables and the games are original (apart from AR, which is the last version, btw).

Can anyone try if the problem is only mine or give me some advice? I'm stuck at eternal darkness and I want to finish it without restarting it.

Thank you!

 

I've tried 1.14b and 1.14c (the latest)

 

mmhhh, I'll try it when my sister get away from the TV!
Thank you!

[edit]
Still no luck... should I try the standard cables?
