Nintendo once again gives cover in the fight (endless?) Against linkers, with yet another firmware update for 3DS. Officially, it is supposed to improve system stability, but it is of course obvious unofficially, it is neither more nor less than blocking the use of linkers.
It is of course obvious that before updating your console 2.1.0-4, we must first think about updating your linkers (provided they have the appropriate update)! The early returns would suggest that Nintendo was not so bad this time, and that most linkers are still functioning properly ... to be confirmed.
