Facening de Hyoujou Yutaka ni Inshou Up - Otona no/Face Training: Facial exercises to strengthen and relax from Fumiko Inudo Facening

is a Japanese (later English too) face training game/software for the Nintendo DS and later rereleased under the English name for the DSi. 

I've REALLY been into the camera accessory that comes with this game/software and I think it may be my favorite Nintendo DS accessory.

If I went back to 2006 at my current age I most likely would have bought this for my original DS, but in current day it is pretty useless if you own a DSi, 3ds, 2ds, 3ds xl, new 3ds xl or new 2ds xl (which I own).

I just find this little gadget VERY interesting. And even in current day I under one someone would purchase it.

I think if I had disposable money I *may* considering getting one of these just to have the thing and use it like once. XDD

Realistically though, for people in MY position (people with a modded 3ds *family* console) should really just get the ROM of Face Training (from a legal copy of the software and dumping it) and just use the camera facing the user when holding the console regularly. I'm sure it'll be the same with the DSi or 3ds family of consoles.

In conclusion I think this is a useless be very cool piece of Nintendo DS history and it's definitely something I really do love no matter how useless it is in 2023.
