Download don't work

I have DS Lite, but I cannot get Spiderman 3, Spiderman friend or Foe and Goosebumps Horrorland work, however I have MarioKart, Ridge racer and etc. are working fine. Those that are not working came from this site. those that are working can from "Nipper". Is there some special firmware or other wear that I need?

What flashcart are you using?

Did you remember to extract the game from the rar file?

Check out the Common Issues thread:

All files on Romulation are compressed to save space and to give you a faster download, this means that when you complete your download you will need to extract the .nds file from the .rar file.
There are no known bad NintendoDS files on Romulation. If (after extracting the game and following the advice that the beautiful TirithRR has pointed you too) you still have problems please feel free to add more info to your problem on this thread.
