Hardware 3DS XL spouting IR error

[pasc]

Well, I usually don't use every and all features of games I own.

However in Pokemon X's case I felt like trying that tourney thing at the start screen.

Turns out it uses some fancy Infrared.

However I always keept getting this (sorta):

An Error occured.

The Infrared-Sending-Receiver is probably damaged.
Please retry all steps up to this result.
If the problem can't be solved, please contact the Nintendo customer support

I have to add, that I added the nand dump mod to this 3DS XL.

Everything works fine, cameras, slidepad, d-pad, wireles and local lan.

Only games using IR will trigger this error.

My other (normal) 3DS works fine.

I even went ahead and swapped the IR Module between both systems - to no avail.

Thanks for reply in advance.

It might be only a minor annoyance, but still.
