Nope.
Except when using a forwarder you're not actually launching a title installed to the 3DS. All a forwarder does is launch a title on a flashcart, and that title isn't seen by the 3DS. I should have clarified earlier. The forwarder title itself is immediately closed after launching into TWL, and this is why it isn't logged.But cartridge DS titles show up however, there must be a way to circumvent this!
Proof
I don't own the cartridge for any of these DS games.
Oh, so you're using a flashcard.
You said that the playtime doesn't show up on Activity Log.
Is the title recorded there with the playtime of 0:00, or the game isn't on Activity Log at all?
Along with this, emunands have become unnecessary in recent months. They take up an extra gig or so on the sd card, and provide no extra brick protection than just using your sysnand alongside b9s. What i suggest you do is ditch the emunand entirely by backing it up and restoring it over the sysnand, and installing b9s as your main exploit. If you're on a9lh right now, you should follow this simple guide to switch: https://3ds.guide/a9lh-to-b9s
