GTA: Chinatown Wars save file problem

My creates the save file, and then it goes to a black screen that says
The save file could not be accessed. Please turn the power off and reinsert the DS card.
I did that like 8 times.

I think that's because GTA:CW has an Anti-Piracy software that recognize if you are playing an original cartridge or just a rom.Here it is the thread where you can find broad information on how to bypass it:

You should get the new emulators or change the NDS Cartridge Media Backup to a different one cause every game has a different save type

For the next person who says "PIRACY" I just might come after you. there is no anti piracy not one, not even if they announced it because its like playing a Armorgames swf game on a swf player [It will tell you to go to armorgames], but if you play it on your internet browser you avoid that, but it works vice a versa.Meaning, playing on a emulator avoids that problem(If it exist), why? cause whatever "Anti-Piracy" software isn't on the game its actually on the console [that would only make the game bigger and waste time, compare the ratio Console:Cartridge] so its probably "Anti-Piracy" firmware (the software on a console) meaning you need the patch to avoid the "Anti-Piracy" on your console. Its like putting a chip in your PS2 and you know what that's like.
