Eye position not printed outside of the emulator

Bug Report

Error code on both lenny_qtm_movement and eye_position

QTMU_GetTrackingData from eye_position and lenny_qtm_movement_naive return a weird error code 0xd8e007f7, that I failed to understand.

This did only happen when testing on my 3DS, not in Azahar emulator, debugging it show that it happens after branching with lr = 0x100034 for both.

For lenny_qtm_movement, key A stops the rotation but Key B doesnt seems to work using the 3DS

Eye Position not rendered

Furthermore, eye_position seems to be working on the emulator but not in the 3DS (no position is printed on the upperscreen).

I did change eyeTracked to headTracked here as the field changed in libctru.

Environment?

I am using the latest devkitPro toolchain (ARM r67.1-1, libctru 2.7.0-1) on Archlinux, using the patch and an old 3DS XL (EUR).
