The i Touch2 is the DSi-compatiable version, which shares the same loader.
Official Site The Supercard Team's Slot-1 card series. The DSONEi is the DSi compatible version of the card.
Original Announcement and Source The Wood R4 loader is a newly released loader for the original R4 (NOT any clones).
There are 3 editions of this particular card, the R4i, the R4i SDHC, and the R4i RTS, the latter of which supports Real-Time Save. It's a mirror of every DS flashcart firmware and software file that I can get my hands on. M3 Sakura is a newer official loader for the M3 Real.Because a large majority of these cards come from Asia, the servers the files are hosted on are slow, unreadable and unreliable for the rest of the world. I also keep a complete version archive, just in case anyone needs old versions and the developers' sites don't keep them. Co-developed by the author of Moonshell, it has a new GUI with integrated media playback functions.Official Site A more recently released card with open source code. Similar to the i Player and DSTwo, it has an onboard CPU for tasks like native video playback.Official Site 1, Official Site 2, Official Site 3 The i Touch DS is a 'budget' card from the M3 Team with all the standard features, plus a 'shortcut' feature that allows users to create quick shortcuts to their favourite apps.
