Well, the Supercard DS is actually already shipping.
Supercard Store will have them in stock from Monday 18th Dec 2006, according to their website. Also HopeBuy are actually shipping orders placed with them immediately.
There are already people on SCDev.org that have them in their hands, but were unable to use them until today as there was no firmware for the Supercard DS.
However that has been resolved by the launch of both the Chinese and English versions of the Supercard DS OS V1.0 and the Supercard DS Patching software V2.57.
Both these softwares are available to download from the Supercard website.
The OS V1.0 should be copied onto the root of the MicroSD memory card. The Supercard DS has a mircro firmware, so relies on the OS to run everything.
The Patching software is optional use, and is only needed if you want the extra things like Soft Reset and Save Direct to memory card.
Also Supercard have released a new IO Driver for the Supercard DS. There is now a version of the IO driver for the Slot 2 devices and an IO driver for the Slot 1 device. Hopefully the new Slot 1 driver can be implemented into a lot of the homebrew apps fairly quickly and also in to the FATLIB drivers.
Hope this info helps everyone.
Cheers,
Ancient Imhotep.
