Get the latest usrcheat.dat from http://cheats.gbatemp.net/ and place it in your _system_ folder. For issues on cheats not appearing, read the Common Issues https://www.romulation.org/forum/index.php?topic=1462.0 If you want to add them manually, then yes you can. Modify the usrcheat.dat using R4CCE and add your codes, or patch the ROM with DSATM for example.
