Ya, sehr gut aber ich habe nicht cubic ninja
Dans la page que j'ai linké plus haut "usage notes for sdiconhax", c'est ecrit noir sur blanc:
With sdiconhax installed, when Home Menu does a normal boot all writes to extdata SaveData.dat are blocked. This is only for normal boots, not when *hax payload was booted from menuhax.
This had to be blocked because the haxx data was getting reset every time Home Menu wrote to this file.
This blocks anything from being done with this file, hence you can't run menuhax-install/deletion with this unless you booted *hax payload from menuhax.
Also note that you can't do/use any of the following without Home Menu entering a crash-boot-loop:
exit from hbmenu for returning to Home Menu, menuhax-thread hax-payload boot(due to restarting homemenu), or returning from any system-applets on Old3DS(web-browser etc)
