Or it could be just a firmware problem...

"Ok lets get this straight IT IS NOT A COPY PROTECTION! Since at the beginning of the game I couldnt even start it. I updated my firmware and encounter the same thing.... But.... my friend who has a cycloDS never encountered this problem. So far its been dated with R4 and M3 but not CycloDS. Apperently this is a firmware bug....R4 and M3 are almost the same firmware there for the bugs.
It could also be the ones getting are European DSes wich is also a bug I noticed in M3s. Sometimes when your DS is european and the ROM is USA. The game freezes or gives weird bugs.... I hardly think this is a copy protection its a bug that inniates the end of the game wich I hade with Star Fox 2 on an emulator once. If you held start during a level change you suddenly got END SCORE ENTRY and CREDITS... So this is a FULL BUG in the ROM."

Actually it's not anti-piracy as many including myself first thought, its just a bug in the firmware that makes the game skip back to the ending, which would obviously take you back to the loading screens, anyone with an emulator has surely experienced this, it would happen in starfox 64 everytime you pushed the start button, so its simply a flaw in the R4 and M3 Firmwares although i should just say R4 since M3 is just a copy of the firmware, A fix should be out within the next few days anyways.
Truth is theres in absolutely no way Nintendo can stop the piracy since its impossible for them to tell if your using a flash cart or not, they both operate in the exact same way."
