NDS games that does not work

I have just downloaded 82 DS games for my R4, although it hasn't arrived yet (will get it in a few days)...My question is: Is Chrono Trigger the only game that has an anti piracy implementation? And is there any games that does not work like normal? I have heard of some minor flamethrower bugs in GTA: CT... any other games at all that does not work as they should?

There are plenty of games that have anti piracy protection, and depending on which of the clone carts that stole the R4 name you bought you might not be able to play some of them.Reading the common issues thread in the technical help section will go a long way to fix a lot of the problems though.
