I have taken a bunch of photos of it and plan to add descriptions for all the sections, but it might take some time since i'm don't have as much free time as before.
First, a photo of the contents:
English and mine also came with a black strap with the Supercard logo engraved in it. In other photos appear different color straps, so i'm not sure if they will also come in those colors, but the black one looks pretty nice.
The front and back of the card:
The DS Two compared with the DS One SDHC:
The memory card slot is spring loaded, just like the other Supercards, the spring seems a bit stronger than the one in the DS One SDHC.
Another photo of both cards, this time also showing the strap that came with mine:
The selection screen:
loading time is pretty low). The available options are DS_Game, GBA Emulator, Moonshell, Slot 2 GBA and Slot 2 NDS.
Slot 2 options are to be used when a slot 2 card is inserted in the DS (for DS Phat/DS Lite), in my case they booted my Supercard Mini SD card. I can't test if it works with other slot 2 cards, it would be useful if someone can test them.
DS_Game allows to load NDS games using the DS Two, Moonshell and GBA Emulator are self explanatory. Each option has a different icon.
The gba emulator intro screen and the emu options:
To load a game you need to use the New option and look for it in the card.
Loading a game:
helps to run a game a bit faster by not loading some of the frames (setting it too high might make the game look choppy), and i think that sound switch allows to enable/disable sound, tough i haven't tested.
The save state section:
The cheat section:
cheats in the gba games, i haven't checked details about the format atm, so i can't really tell a lot about it.
The tools section:
nds of time is a compatibility fix).
The others section:
The DS_game section:
Skin, Language, System Settings and Help). It came with two different skins, named Silver and Pink, the one shown here is Silver, and in the next photos i'll be using the Pink skin so you can check both of them.
The available options when showing the roms are list w/icons and icons, it's possible to switch between them pressing Select.
The available languages (using pink skin):
ingame menu (pressing L+R+Select+Start while a game is running):
