Softmods For Microsoft Xbox
Softmod is also a term used to refer to modifying a Xbox without the use of a mod chip.
Softmods for Xbox used to include a font exploit installed through exploits in savegame code for MechAssault, Splinter Cell, and 007: Agent Under Fire. Usage of the Splinter Cell disc is generally recommended as any version of the game will run the exploit, whereas certain production runs of Mechassault and Agent Under Fire are needed to use the exploit. Originally, via a piece of software called "MechInstaller" created by members of the Xbox-linux team, an additional option could be added to the Xbox Dashboard for booting Linux. The Font-hack works by exploiting a buffer underflow in the Xbox font loader which is part of the dashboard. Unfortunately, since the Xbox requires the clock to be valid and the dashboard itself is where you set the clock there is problem if the RTC backup capacitor discharges. The Xbox will detect that the clock isn't set and therefore force the dashboard to be loaded which then promptly reboots due to the buffer overflow exploit. Upon restarting, the Xbox detects the clock is invalid and the process repeats. This became known as the infamous "clockloop".
