Pretty much what it says it is. It loads GW patches and cart redirections on your sysNAND. So you can use the GW cart on sysNAND. (TBH all I use it for these days is a quick and dirty way to install a CIA manager on sysNAND without going through the whole injection process) Note that using sysupdater/updating FW on GW's sysNAND will cause bricks.
GATEWAY – Select button replaces Game Slot on Home Menu with selected ROM file SYSNAND - Explained above (Retail cartridge can be used in Game Slot with sysNAND’s default save encryption) 7.X- Classic Mode Retail cartridges can be used with < 7.x save encryption (GW saved games in this format for a long time) 7.X+ Classic Mode Retail cartridges can be used with > 7.x save encryption
I haven't got a GW card, but on the GW website with my Game Cubic Ninja I flash the QR code, a message of installing exploit succefully was display.Does it mean that my sysnand is in GW mode?
