Hacking Ds lite ez flash

[Newbasaurus]

Hi all. I am new to this so go easy on me. I am trying to use cheat codes for pokemon fire red. I am using a Ds lite but the cheats don't work. Are they only for a Game boy advance console. I watched tutorials on youtube and everyone uses a GBA and not a DS lite. Is that my problem ? Everything is installed and I can play the game but the cheats don't activate. Yes I did do the L R And start to turn them on. Thanks for your time.

The cheat engine works on GBA and DS(DSLite)，but I can not ensure each code can work properly, not related with consoles, but the code itself.
