Nesds not working on R4i, see menu for half a second and screens goes black

Hello all, I'm sure this has been asked here a lot of times but I don't see a thread that solves my problem. I installed Nesds on my R4i card and all I see is two black screens on my DSi. I see the nesds menu for about a second and then the screens go blck and I have to reset. I patched the nesds.nds file but now sure I'm doing it right. The same happens with the SNES emulator. I'm pretty much new on this stuff. I did installed the SEGA emulator and it works just fine. Can someone maybe tell me what am I doing wrong or tell me by steps how to do it? I have been trying for a couple days now and not sure if I'm missing something?

Thanks!
