This tool helps you fix the issue where files in your NBA 2K26 mods stop working properly after the 1.4 update patch. It's actually just that the game has gotten stricter about file structures instead of disabling your mods.

### Download
https://www.mediafire.com/file/ofpkpr4i ... 2.zip/file


### How to use
Just Drag & Drop IFF files or folders containing IFF files (it'll scan all IFF files inside) onto this EXE.
(You can check out the two GIF previews for reference.)

> **For gamers**, you can simply drag your `mods` folder in, and it'll handle all the IFF files at once.

> **For modders**, you'll want to use this tool to make sure your mods work fine after the 1.4 update.

### Details

In the NBA 2K26 1.4 update, it looks like 2K traded some compatibility for better file loading efficiency, like dropping support for certain compression formats. This tool helps fix the factors in IFF files that affect mod loading:

- ZIP format: My File Explorer uses libzip to build ZIP packages for IFF output, and coincidentally (or not), IFF files packed with libzip work just fine in mods.
- In most cases, if subfiles in an IFF have the same filename but different extensions, it'll make the whole IFF invalid—like `aaaa.bin` and `aaaa.bin.bak`.
- It no longer supports the old setup from previous 2Ks where duplicate object keys in SCNE were treated as arrays. (Starting from 26, VertexStream in SCNE has switched from duplicate-key objects to proper JSON arrays).

So I whipped up this simple fix tool to quickly handle the issues I've found so far. The processed files will overwrite the originals, so you don't need to do anything extra.

Thanks to `EGS-MLLR`, `顾羽铮`, `小至尊`, and others who helped with testing.

Since we're not sure if 2K will revert to the old way in the future, I put together this basic program for now to keep mods usable. If they stick with this approach, I'll look into more convenient options later.
