The SuperCard DSONEi is a Slot-1 flashcart solution, made by the SuperCard team. It's exactly the same as the SuperCard DSONE, but made to work with the DSi. However, it can only use the DSi's DS mode, because DSi mode hasn't been hacked (yet). After the DSi's 1.4 Firmware update, it was blocked by Nintendo to make sure it didn't work, but thanks to a 'Firmware Writer' included in the package, team SuperCard got it working again by changing the cart's header to the header of Star Wars Lethal Alliance. This makes the cart show up in the DS/DSi menu as if it actually is Star Wars Lethal Alliance. Recently, it got a OS update, as did the DSone and the DSONE SDHC. The new Operating System (called the Evolution Operating System, or EOS) is a major improvement on the old OS, which was based on Moonshell. Because of that, with the old OS you could play music and DPG videos, show pictures, read text files, etc. Now you can't do that anymore, you can only load ROMs.

This is because of the way you can run games, in clean or in patch mode, and because of the save size you can set for the games.

Evolution OS FAQ

Taken from here. Edited here and there.

Why does the message "No Find English/Chinese/Japanese Ver.!" appear?
That means the OS is not an English/Chinese/Japanese version. Please download English/Chinese/Japanese version OS from E.g. if you have a Chinese DSONEi, you have to download the Chinese OS for the DSONEi.
Can I use the saves of old SuperCard product?
Sure, and very easy. Just rename the save file as the same filename of the nds game and put them in a same folder, e.g. if your game is 123.nds, then rename the save file as 123.sav.

How to update the OS (operating system)

First, download this file if you have an English DSONEi, or this file if you have a Chinese DSONEi. Extract it using a program like WinRAR. Inside will be a folder called en or chs. Open the folder. Copy the files inside it to the root of your microSD card. Finished. That was easy now, wasn't it?

How to update the firmware

If you update your DSi to the 1.4 firmware, you will notice the DSONEi doesn't work anymore. Don't worry though, because that's what you got that handy-dandy firmware writer for.

Firmware writer

First, you will need to download this file. Extract it using a program like WinRAR. Then, put the extracted file (updateen.bin) on the root of your microSD card. Put the microSD card in the DSONEi, then put the DSONEi in the firmware writer. Put the firmware writer in a powered USB port (this can be a computer's USB port, a USB charger, etc). You'll see a light flashing. This means the fireware is being updated. DO NOT remove the firmware writer from the USB port during this time, because you might risk bricking your card. This process takes about 8 minutes, it depends on the speed of your microSD card. When you see a green light, that means the updating is done, and you can safely remove the firmware writer from the USB port. However, it could be that you just see a red light, this means that the updating process has failed. Try it again until it works. Now, when you put the DSONEi in your DS/DSi and turn it on, you won't see the SuperCard logo anymore, but you'll see Star Wars Lethal Alliance instead. Don't worry, it's still your DSONEi, but with the header of the Star Wars Lethal Alliance game.
