• Rename the arm9loaderhax.bin that you currently have to Luma3DS.bin
• Copy the arm9loaderhax.bin and a9lh.cfg from CTRBootManager to the SD card root.
• Rename Gateway's arm9loaderhax.bin to GW.bin and put it on the SD card root
• Edit the a9lh.cfg file to have these as entries:
Code:
[entry]
title = Luma3DS
path = /Luma3DS.bin
offset = 0
key = -1
[entry]
title = Gateway
path = /GW.bin
offset = 0
key = 7
This will give you the choice of booting to Luma3DS (default) or Gateway.
You can auto-boot Gateway when pressing the DPAD Down button on boot (that's what "key = 7 is for). If you want to use another button let me know and I'll tell you what number to put next to "key =" on the Gateway entry.
