Revision as of 02:38, 19 March 2010
Nintendo Zone is the successor of DS Download Station, the latest revision in the Nintendo Spot series. The predecessor of Nintendo Zone in this series is DS Station, and the first revision in this series is Nintendo Spot. Although Nintendo Zone is the latest revision in the series, most game stores still use DS Station. This series downloads DS demos from an Internet server, rather than from a local DS host. Nintendo Zone locations have additional company-specific content. Companies can use this for information about the store/location, coupons with McDonalds, mini-games, etc.
Client usage
Unlike DS Station, the Nintendo Zone client is rigged to only connect to an AP with a certain Broadcom tag. In other words, the client is rigged to only work with a certain router. When the AP has the correct SSID, WEP key, and Broadcom tag, the client attempts to connect to the AP.(WEP key is generated from the SSID, Nintendo software can automatically connect to these APs without any configuration.) When the DSi is in range of a Nintendo Zone AP, sysmenu will display a message that you're in range of a Nintendo Zone AP. The hidden DSi Nintendo Zone client will then appear in the menu. The client is basically a NetFront browser rigged to only work with certain APs, and with the capability of booting RSA-1024 signed NDS software. The client seems to only support Nintendo's custom NTFA file format for graphics.
Versions
Version 3.0 of DSi Nintendo Zone client was released with the February 9, 2010 update. The Japanese client was updated to v3.0 on January 8, 2010. It is unknown what has changed.
Exploits
DS Station's web browser uses NetFront 3.3. This browser version has a stack smash bug in a function writing the URL from a tag field's value to the stack. This bug is present in at least one function, it's unknown if other functions have this bug as well. It is currently unknown if Nintendo Zone uses a newer NetFront version with this bug fixed. A Nintendo Zone exploit couldn't be easily used by everyone, as Linux and a compatible hostapd wireless NIC is required. An SSID, and the WEP key generated from the SSID, from a real Nintendo Zone/DS Station AP is required. At real Nintendo Zone APs, a laptop running Linux with a wireless NIC supporting monitor mode would be needed. This exploit would be meant more for reverse engineers.
A DS Station exploit has been written by Yellows8. This DS Station exploit can't be adapted to Nintendo Zone until an Nintendo Zone AP capture and Nintendo Zone binary are obtained. A volunteer to capture Nintendo Zone AP traffic and the WMB binary was found a long while ago, but it is unknown when he'll capture. Perhaps sometime this month(March), but it's unknown. This exploit can only be used with html that is transferred over http. The html for the index main and sub screens is transferred over https. However, the html for the main screen for the pages after the index,(main server and third-party companies websites) is transferred with http. The sub screen html is transferred with https, with the main server. Sub screen html with third-party companies is transferred with http. Strangely, the back link from the menu after the index page for the main server, the main screen html URL uses http, rather than https. Currently the exploit only changes the sub screen display to a tiled hex dump display.(It's supposed to anyway, gfx isn't working right.) A means of bootstrapping homebrew is being worked on. Bootstrapping a .nds embedded in the exploit has been done somewhat successfully, but Arm7 booting seems to be broken. NetFront limits the size of html files that can be downloaded. The max size of a LZSS compressed .nds embedded in the exploit is roughly 200KB.
