Important information
By using CFW on sysMMC, it is possible to move save data between your emuMMC and your sysMMC. This process, by itself, should be safe in terms of not getting banned: running homebrew applications like checkpoint through the homebrew menu on sysMMC is not known to cause bans. However, the problematic element you may encounter is the save data you are using. If you are transferring modified save data from your emuMMC to your sysMMC and you plan to use this edited save data online on your sysMMC, you should proceed with extreme caution as this may attract a ban. Using the edited save data on an offline game may still pose a risk if you use it on your sysMMC due to the way telemetry and logs work, although this varies depending on the game
