Dedicated tools can detect if a header is present and strip it safely:
Here’s a technical guide focused on the — a niche but important power electronics topology used when converting Switched-Mode Converter (SMC) outputs into a Switched-Function Converter (SFC) format, typically for power conditioning, impedance matching, or system integration. This works when only the extension differs and
Modern, highly accurate emulators (like bsnes) exclusively demand .sfc files.

The Ultimate Guide to SMC to SFC Converters If you are a retro gaming enthusiast, you have likely encountered two primary file extensions for Super Nintendo (SNES) ROMs: and .sfc .
