Nintendo DS lite queries?

Nintendo DS lite queries?

Hi people out there!

Recently, I have been thinking of getting a DS lite. I did a bit of research and saw some things like R4/ dstt.

I know the purpose of the cards mentioned above – after inserting the micro SD card into the dstt, inserting the dstt into the console will allow me to play whatever is on the SD card. Inlucding

I heard that the new DS consoles nowadays can no longer read these cards. Is this true? (I don’t really care about DSi though, I just want to know about DS lite) Because if so, I may have to reconsider my decision on whether I want that console or not..

Thank you for your time, and please pardon my English
