'''Savezelda''' is a family of exploits that take the same general form and use some common code to load [[homebrew]]. The name comes from the original savezelda exploit, [[Twilight Hack]], which was a Legend of Zelda exploit.

'''Savezelda''' is a small loader designed to be bundled with exploits. The name comes from [[Twilight Hack]], the original exploit to use this loader. Its sole purpose is to load <code>/boot.elf</code> from SD or [[USBGecko]], SD taking priority. Because the [[Wii Mini]] does not have an SD slot or a GameCube memory slot, this loader is not Wii Mini-compatible, which is why [[Bluebomb]] has a custom loader.

==How these work==
 
These exploits take advantage of the fact that the Wii does not implement any address space layout randomization (ASLR), which means the moment a size isn't checked before something is loaded, the memory address where this is loaded is predetermined, so a fixed amount of padding can be added before a return address on the stack can be overwritten, which will happen perfectly every time. Doing this causes the system or game to send control over to the desired area. These exploits also package some code that can be returned to, which allows them to take full control over the Wii, and load other things such as the HackMii Installer.

Savezelda is a small loader designed to be bundled with exploits. The name comes from Twilight Hack, the original exploit to use this loader. Its sole purpose is to load /boot.elf from SD or USBGecko, SD taking priority. Because the Wii Mini does not have an SD slot or a GameCube memory slot, this loader is not Wii Mini-compatible, which is why Bluebomb has a custom loader.
