From a manufacturer’s perspective, solid firmware means control and, when that company is Nintendo, control means the prevention of piracy and repurposing of hardware. Without reliable firmware, sophisticated computers, smartphones and consoles are unable to carry out their most basic functions, including the ability to boot up.įrom a regular customer’s perspective, firmware should be imperceptible and totally reliable. Custom Firmware & Sigpatches – How We Got Thereįirmware is a type of software that resides in non-volatile memory, with a PC’s BIOS chip being an obvious example. It involves so-called ‘sigpatches’, software tools that play an enabling role in defeating access controls. These days Nintendo has multiple attack vectors to cover, from bringing down commercial groups such as Team-Xecutor to blocking sites that distribute pirated Switch ROMs.Īs a result, the Japanese gaming giant often finds itself taking action under the DMCA but as a case from late last week shows, that isn’t necessarily straightforward. Nintendo has been tackling videogame piracy for a very long time but a lot of water has gone under the bridge since the simplicity of the SNES-based Super Wild Card.
