In-depth: ELF - The Extensible & Linkable Format
Description YT
ELF files are everywhere: From your PS4, to the Wii, to any Linux device out there. In this video we explore the Extensible & Linkable Format, and understand how it works - on the byte level!
Errata:
- At the beginning I say extensible while displaying executable and linkable file format - Extensible is the old name, nowadays ist called Executable. Must’ve gotten confused :)
