Question.
How can I setup Decrypt9 to run in the latest Luma3ds CFW with Arm9loaderhax?
New 3DSXL Ver.11.1.0-34 U
Thanks

Thank you got it work.You simply download Decrypt9 from the GitHub page here and then copy the .bin file to your SD:\luma\payloads\ folder. Should be named button_decrypt9WIP.bin where button is which button you wish to hold while starting the 3DS.
If you follow Plailect's guide here it would take the place of hourglass9 and be called start_decrypt9WIP.bin
Be sure you also set the files9 folder and contents up according to playlet's guide as well.
