For those with the Gateway Flash Cart, for a easier way to find Codes for the latest Release, go here. Codes are being updated almost every Day

So far, 33 Games have Codes that can be used such as StarFox64 3D, DKCR, more Codes for SM3DL, and many others

NTR Cheat Codes work with Gateway and so far, can use both GW Cheats together with them. Simply Install NTR, run it, then start a Game that has Cheats. However, http://www.elotrolado.net/wiki/Cheats_para_NTR
Does not have all the Cheats from this Page
http://www.speedfly.cn/category/game/nintendo/3ds_cheat
Also some of the Cheats on the last Page do not have Commands listed for enabling Cheats.
