How do I add cheats to the R4?

;D

Get a usrcheat.dat from http://cheats.gbatemp.net/ and place it in your _system_ (or equivalent) folder. For issues on cheats not appearing, read the Common Issues https://www.romulation.org/forum/index.php?topic=1462.0

if you need to edit e.g add more to thelist pm me :)

you can make them yourself ( takes much time0 or get them from a ds firmware site like gbatemp.net go to r4-cheats and choose one of the latest
but cheatin is boring
