All of the mario games I have for the DS that I downloaded from this site cannot perform the "DS download play" feature. WHY?! Everytime I try, it says connection error, please help. I am also having the same problem with CAll of duty 4.

Which flashcart are you using? Some flashcarts and some games dont support download and play, also if you trim your roms you often get errors, try using the full rom if you currently arnt. Also make sure you have the latest firmware.

Im using a Super Card DS One with a Kingston 2gb micro SD if that answers your question. And also how do i check to see if my firmware is up-to-date

When you run your Supercard, it should say your firmware version somewhere on the menu. Check by clicking Linfox Domain in my sig. DS ONE has about 80% download play compatibility, and it says on the GBATemp review that Mario Kart etc. doesn't work so maybe that's the problem. Or it could be your connection.
