Need help with Final Fantasy Echoes of Time

I just started playing the game like 5mins ago. when i got to the save point, it says, Save error, reinsert the card. i was playing the game on an R4. Can someone help me with this problem?

It is a Piracy Protection in the ROM :) You'll need to update your cheat database 'usrcheat.dat' from http://cheats.gbatemp.net/ and then enable the 'Game Fix' code to get past this issue. If you find that you cannot seem to enable it, please read the Common Issues for that covered problem https://www.romulation.org/forum/index.php?topic=1462.0 :)

TY.
