No, not installed 9.9 fromcart. This N3DS 9.9 belongs to my friend. It was bought at 9.5 firmware. Then updated to 9.9 to access Eshop when Smealum first hinted at freehax with Ironfall Invasion 1.1 game. He's gonna travel to his granddad during Thanksgiving so he may hunt for N3DS <9.3 there (a small town). In case he can find N3DS <9.3, he wants an option to keep the Ironfall Invasion 1.1 game on his EMUNAND (wishfully thinking until 9.3+ kernel exploit then transfer to SYSNAND then) before selling his N3DS 9.9.
Would be a waste to delete a free entry point (which works for the latest firmware), if transfer is not possible.
