This is AK2i。
This is the first type of AK2 and AK2i. It has a window in the shell.
Please notice the banner of the chip which AK2 and AK2i used. It called "Actel".
This is the second type of AK2 and AK2i. There's no window in the shell anymore.
Chip inside:
We're selling this type of no window now.
The chip on PCB of two types of the AK2 and AK2i.
This is another side of PCB. 
AK2 and AK2i both use the chip of "SST" and it's 48 pins. Some batches of AK2 used other banners of 48 pins chips. But all AK2i use this "SST" 48 pins chip.
Conclusion: 1. The chip on the back of the PCB is "Actel" or little black glue circle. This is very important.
2. The chip on another side of PCB is a 48 pins chip of "SST". Some batches of AK2 used other banners of 48 pins chips. But they're all 48 pins.
3. Please refer to the 2 items above as the main symbol of real AK2 and AK2i because the package of retail had changed many times.
We offer one year warranty for real AK2 and AK2i. You can contact your reseller for a replacement for any issue of the real AK2 and AK2i. We do not guaranty any safe use of firmware on fake AK2 and AK2i, and on your DS or DSi. We won't offer one year warranty for fake ones in any case. Please pay attention when you're buying Acekard.

Fixed saving issue of 3690.
Warnning! Please delete the old 512k save file before using this new menu. And 3690 uses a save file of 256mbit. So it'll take a very long time to create new save file when you first entering the game. Please be patient.
