What can I do to make A R , Gameshark , or AR max code in my R4 ?

I want to give my ori pokemon diamond with mystery gift to obtain darkrai,shaymin , and arceus.Please help me.

I don't think a having a R4 works with AR sorry I tried too.

R4 has support for Action Replay cheats. I thought you wanted to make your own code, which generally you can't do.. Anyways, it depends on what you're using. Emulator, then yes, if you use a flashcart, most of the time.

thanks didn't know that. Thats why I think this is a very good site everyone is willing to help if they know something.

For a patch editor thing this is the link- http://www.mediafire.com/?zyrndlymomd
Just have this and your save on the desktop and select the right save on the application and you can edit your save and then put it back to your r4, in the application if you look enough there is an event part or you could use item edit either way...
For a cheat.dat you can download them on other websites like the official r4 website, e.t.c
(cheat.dat's have ar codes for your games but not all and you can edit them yourself if you know how)

Oops, forgot to read the whole title, if you still are stuck at adding cheats, go to my awesome tutorial with pictures.https://www.romulation.org/forum/index.php/topic,6343.0.html
