v9.9 dummy web-browser
The gamecard v9.9 sysupdate included with some games contains a dummy Old3DS/New3DS web-browser. The *only* thing this title does is display the same message listed in the above forced-update section. The message files in RomFS *only* contain that message string above. There are no "http" strings in the main codebin, and
RO isn't used either(no CRO data in RomFS at all). Both browsers are internally called "dummySpider".
Hence, if you update your system from pre-v9.9 using a gamecard with v9.9, the system web-browser will be rendered *completely* useless until you install a system-update from CDN(no network requests involved here).
