From d171409f29ce3d8bcf7ed6ce16392b4b4ec97c4b Mon Sep 17 00:00:00 2001 From: Subv Date: Sat, 26 Nov 2016 23:13:40 -0500 Subject: Kernel/Loader: Grab the system mode from the NCCH ExHeader. 3dsx and elf files default to system mode 2 (96MB allocated to the application). This allows Home Menu to boot without modifications.
