Babelfish is a tool by fail0verflow that was the first full custom firmware (CFW) for the Wii. It works similar to installing a cIOS in every slot, except this tool actually makes no changes to the NAND.
Technical explanation
To avoid modifying the NAND, Babelfish instead patches the IOS it is told to load on-the-fly such that when __IOS_LaunchNewIOS
is called, the IOS loaded is replaced with the same loader stub that initially loaded Babelfish, maintaining the illusion of a cIOS network without causing permanent damage. For this reason, it was initially called "IOS Virus."
Patches
- Redirects any IOS loaded by
__IOS_LaunchNewIOS
to Babelfish's loader stub - Redirects any IOS reload to the custom loader
- Sends debug output to USBGecko
- Custom IPC hooks (made redundant by ahbprot):
- device_open
- new_thread
- ppc_boot
- arm_boot
- load_elf
