So I'm running the latest stable version of Luma and want to install CTRPluginFramework but it requires me to replace my boot.firm, which is no big deal if I eject my microSD card... However given the pain in the ass to do that on a N3dsXL I generally always use the built in microSD management wi-fi file transfer to put files onto or off of the SD card. Boot.firm strikes me as more system critical though and I want to know if I need to physically eject the card or if wi-fi is safe.
