R4 card on DS Lite not recognised

Hi. My son & daughter both have DS lites. My son's in black. My daughter's is pink. I have an R4 Revolution card (version 1.32b). It works perfectly in my son's black DS Lite, but when I put it in my aughter's pink DS Lite, it says No Cartridge inserted. If I check the firmware on both using the picto chat method, and both show the same purple colour. Has anyone else seen this problem? Is there anything I can do to make the R4 card work on the pink DS Lite, while still working on the black one? Cheers

 

That is strange..

But the R4 for DSlite is dirty cheap, why not just buy one. It only costs $2 here

 

I would buy one if i knew it would work. But the pink ds doesn't recognise my sons r4, so would it recognise a new r4 which would be the same as what my sons got

 

i think you should buy a new card.n
