Troubleshooting the R4 3DS Card Error: “Can't Open _ds_menu.dat”
Introduction
The R4 3DS card and R4 card are a popular flashcard that allows Nintendo 3DS users to play a wide range of games and use various applications. However, like all technology, it can sometimes run into issues. One common error is the “can't open _ds_menu.dat” message upon startup. This tutorial will guide you through the steps to fix this error, ensuring a smooth gaming experience.
Understanding the Error
The “can't open _ds_menu.dat” error usually occurs due to issues with the firmware on the R4 card. The _ds_menu.dat file is part of the firmware that runs the R4 card's operating system. If this file is missing, corrupt, or incompatible with your version of the R4 card, the card will fail to boot properly. The missing file is almost always as a result of having either the wrong firmware for the R4 Card being used, or that the firmware files that have been put on the micro SD card are not placed into the root of the micro SD card. By the ROOT of the card, we mean that all files and folders should on on the main part of the micro SD card and not within another folder. Read on for some steps and tips.
