Just bought a 2nd-hand DS lite - Need R4 info

Hi All,I just bought a 2nd-hand NDS-Lite for my daughter and am hoping to buy an R4 card for her. I have a working R4 card for my eldest girls XL, but her card doesn't work in the Lite.I've Googled and found that the Firmware Version is 'V5' (something about magenta (purple) screens).Any info would be appreciated.Ta Pilkojr

You can buy it here, but you should buy an original card, since it's supported by Wood R4.
That way you can basically play all the games without any errors.
Oh, and it's super cheap.

Thank you very much. Just ordered one.
