How do you convert nds to iso?

To convert NDS (Nintendo DS) files to ISO format, you typically need specialized software, as NDS files are not inherently compatible with ISO, which is commonly used for disc images. Tools like "NDSTokyoTrim" can help trim NDS files, while "R4 Converter" or "DS2ISO" can convert NDS files to ISO for use in emulators or other applications. Always ensure you own the original game before converting and using any files.
