3DS homebrew tool to check undocumented DS cartridge data.
Feb 01, 2016 TWLSaveTool is a 3DS homebrew that allows you to read, write, and erase save files from NDS cartridges (just like savegame-manager!) The CIA build requires an access to CFWs. If it's the case, this is the best option; you'll be able to see the awesome banner Apache Thunder made ?. The 3dsx build.
I made this tool to increase the amount of DS cartridges that tools like Checkpoint or PKSM recognize as valid cartridge.
If you had issues with certain DS cartridges with the tools just mentioned, then JEDECheck is the right tool to be used to be able to send us all the data needed to support your carts in future updates.
Usage is very simple: just plug in your cartridge and run JEDECheck. If the cartridge is undocumented, a report file will be generated on your SD card.

Required Reading
All game cartridges contain a copy of the required system version to play it, allowing anyone on a lower version to use the cartridge to update to that version (even without an internet connection).
Note that cartridge updates will only deliver updates to core features, such as the System Settings, Home Menu, etc. cartridge updates will not deliver updates to Nintendo 3DS Sound and Network features, such as System Transfer, Internet Browser, StreetPass Mii Plaza, or eShop.
This means that using a cartridge update from a version containing an older Nintendo 3DS Sound version (<3.0.0) to one that introduced a newer Nintendo 3DS Sound version will break Soundhax! You will need an alternate method of entering the Homebrew Launcher!
This also means that a cartridge update will NOT install a browser if you do not already have one. This will only update the actual system version (for example, 2.1.0-0 -> 6.0.0-0). The last number (the -0) will not change.
Updating with a game cartridge containing the version 9.9.0 or above will remove your browser until a standard online update is performed!
