Hi everyone! I've got the following problem: I have a DS lite I bought in 2007 and an original R4 from the same year. Now, when I try to start up the DS with the R4 in it, it doesn't skip to the R4 menu like it should. It says "No DS cartridge inserted". When I push the micro SD card (Kingston 1 GB or Sandisk 2 GB) a bit further in, it boots to the R4 menu, only to report a "the hardware is not compatible" error. It worked flawlessly for ~3 years. What can be done to solve this problem?
