This thread is for stuff so I can quickly copy and paste it into a common noob question. Rxtools outdated firm You need to switch to luma3ds. Rxtools uses an outdated firm and [game here] needs updated firm [latest luma .zip] Always copy arm9loaderhax.bin to the root of the SD. You don't need to do anything else if you're using ARM9LoaderHax. If you're using menuhax/browserhax/any other *hax that displays the Homebrew Launcher, also copy the contents of the hax folder to the root of the SD. If you are using menuhax and want to boot Luma3DS directly without a boot manager/the Homebrew Launcher, also copy the boot.3dsx from the menuhax folder to the root of the SD, overwriting the existing one. If you're using browserhax without the Homebrew Launcher, or the mset (System Settings) hack, also copy the Luma3DS.dat from the mset-spider folder to the root of the SD. If you're using the mset (System Settings) hack, also copy the Luma3DS.nds from the mset folder to the SD of your DS flashcart, and run it to install the ROP.
