Thank you.
What about savegames?
- Game cartridge using 6.x KeyY played in emuNAND will not work on downgraded console's EmuNAND (Classic mode emuNAND use correct Savegame KeyY on 9.x)
I don't even understand what you're saying. Care to elaborate?
I'll try to explain in an easy way.
Well, games are using different methods and keys to encrypt savegame data.
games using the "6.x" method are using a set of keys available only on SysNAND.
when you are on a 4.5 console (with or without emuNAND) and playing a game requesting the "6.x" encryption key, the key used by the game is read from RealNAND (sysNAND), and the console's NAND don't even know the 6.x key because it's still on 4.5, so it falls back to use 2.x keyset instead of 6.x keyset.
But with updated SysNAND and gateway 3.0, it's now possible to use Gateway Classic emuNAND with console above 6.0
the SysNAND has the 6.0 key, so emuNAND is also using it to encrypt savegames.
All the savegame compatibility depends on the RealNAND version.
Console Real NAND 6.0+ = using new encryption
Console Real NAND 4.x = using old encryption.
if you downgrade from 6.0+ to 4.5, your game cartridge's savegame will not be recognized as it's encrypted with a different key.
and the other way is true too : if you started a "6.x" game on a console with real NAND v4.5, it will not work if you update your console past 6.0
Some games are still requesting the old keys, not all games want the 6.0 keys.
So, games always requesting the 2.0 key work fine whether you are on 4.x or above.
