YS Menu on my r4i?

I'm just asking sause I have heard if you have an YS Menu on your r4 SS/HG work wihthout freezes.
But I have 1 extracted on mine and it doesn't work there always comes an error.
I'm gonna tell you what R4 card I exactly have.
On the card stand : R4i ( works on my ndsi ) When I load the game on my ndsi it's named : R4DS
And on the card stands this webside : www.r4ultra.com
Is there any version of YS Menu what works on it ?
Please give me a site ?
Sorry for my bad English but I'm from the Netherlands. :D
