NX-Update-Checker

A small console application that checks a Switch's installed contents against a provided versionlist for newer/missing updates/DLC, and then writes the titles with newer/missing updates/DLC and the latest version to sdmc:/Available-Updates.txt.

Usage

• In case of no internet connection, grab the latest versions.txt available from the nx-versions Repository, and save it in the same directory as NX-Update-Checker.nro
• Run the nro with your favorite variation of the HBMenu
• Watch the pretty text move across the screen
• Profit(?)

Ignore List

Users can choose to ignore specific game updates and DLC if they choose by creating a file named ignore.txt and filling it out with the following structure:

• For each line a single, whole title ID must be entered for either an update or DLC
• That title ID may (optionally) be followed by any text/descriptor with or without a space after the title ID
• ignore.txt must be placed in the same directory as NX-Update-Checker.nro

An example ignore.txt is shown below:

0100000000010800 Super Mario Odyssey Update
0100E95004039001 Xenoblade 2 Torna DLC
01006A800016F002 Super Smash Bros. Joker DLC

The above ignore.txt would prevent NX-Update-Checker from showing new Super Mario Odyssey updates, Xenoblade 2 Torna DLC Binary updates and Super Smash Bros. Joker DLC Binary updates.

Local Cartridge Version Database

Should a user have a cartridge inserted, the application will populate any bundled update into a local database cart_versions.txt to avoid notifying the user of an update already bundled.
E.g. if there is version v65536 on the cartridge, it will be saved. Then if the cartridge is removed the database will be read and not notify the user of updates for that title unless v131072 or higher is available.

Logging

Users can choose to produce logs while running the application for debugging purposes by creating an empty file named log.flag in the same directory as NX-Update-Checker.nro

Note however, that the application will run much slower while logging all operations it's making.

The logs will be produced at the root of the SD as a file named NXUC.log

Additional Information

This app was specifically re-written to parse the versions.txt posted in the nx-versions Repository, if you provide a versions.txt with even a slightly different format it is likely this application will not parse it correctly.

This app's downloading capability was tested with Atmosphere's prodinfo blanking, incognito and 90DNS independently.

Binary releases are built using switch-curl-7.69.1-1 to avoid connectivity issues with a blanked prodinfo.
