When you have just installed the forwarder, does the image get loaded or does it appear without image? This solution applys for cases when you install the forwarder and the image can't be loaded, and when you open it, it says what you said: "Unable to start software"

The image loads, yeah. I have tried both the online browser generator and the homebrew in the console.

Are you sure your sys-patch/sig patches working? Sounds like you don't have either installed. This is just a spit ball in the dark

Used to have a 420000000000000B folder in my Contents folder which apparently for some reason was preventing me of updating my firmware while on sysCFW, is this the sys-patch you're mentioning?

Hey all. My first post here. I want to share a tool that I've been working on to create NRO to NSP forwarders. I know there's a lot of prior art in this field, but all have been either Windows only or command line only, and that left me desiring a version that worked without installation and worked on all operating systems and has a nice user interface.

So I created this online tool called "NSP Forwarder Generator" (generic name, I know, but I'm not good at coming up with catchy/clever names)!

Some features that I think make this version stand out are:

It's a website, not a program that you need to install, so it will always be up-to-date and works everywhere that a web browser is available.

All processing is done directly in the web browser. Images are processed using the <canvas> HTML element and the `hacbrewpack` tool (which is the central tool powering this) is running in the browser by being compiled to WASM.

A handy cropping interface to fine tune your application title image (on home screen), boot-up logo (top-left) and boot-up animation (bottom-right).

Automatic conversion of the images to the proper size and format that the Switch requires to work with (so no need to worry about troublesome EXIF data).

Convenient RetroArch core path presets selector, to quickly and easily specify which emulator a game should be run with.

I've been using it personally with a lot of success so far, but I am receptive to feedback and/or feature requests. Let me know if you find this useful. Cheers!

this project seems cool!

anyway I can get this to work with mp4 files? I'd love to use my switch as a virtual movie display shelf!
