NX Simple Downloader
A Nintendo Switch homebrew application that reads a download URL from a `.ini` configuration file, fetches the file over HTTP or HTTPS, and saves it to a predefined directory on the SD card — overwriting any existing file.
Features
- HTTP & HTTPS support via libnx BSD sockets and the native Switch SSL service
- Automatic redirects — follows up to 5 HTTP 3xx redirects
- Progress bar with KB counter and percentage (when Content-Length is known)
- Chunked transfer (Transfer-Encoding: chunked) support
- Self-signed certificate support via `ssl_verify = false`
- SD card enforcement — the app refuses to write anywhere other than `sdmc:/`, protecting the Switch NAND from accidental or malicious writes
- Path traversal protection — `..` sequences in `destination` and `filename` are rejected
