Revision as of 04:28, 8 May 2008

These are some currently popular questions in the #wiibrew channel. Remember to read Channel FAQ before you jump in.

General

Are we using the SDK? Is there an SDK from Nintendo for Wii development? Is it leaked?

No, we are using the open-source, freely available devkitPro and libogc.

Are there any homebrew applications available for the Wii?

Many applications are available at the Homebrew apps page.

Will a Wii System Update brick my hacked Wii?

Probably not, however, you must be careful what hacked programs you run on your Wii as the programs themselves are capable of bricking your Wii.

How do I turn off my Wii while in a loader?

Hold the power button for 5 seconds until the Wii powers down.

What if the next Wii update patches the Twilight Hack?

The only way to patch Twilight Hack would be to press new discs or have the system patch the game upon loading it. The likelyhood of the former depends on whether or not they intend to keep fixing bugs anyway -- this hack is probably not enough reason for them to restart production of the discs. (That having been said, there are already two different NTSC/US versions of that game, so a third could be released.)

Patching the game while loading is unlikely for a number of boring reasons. It's a lot of work with very little benefit -- until homebrew activities threaten Nintendo's revenue, don't expect them to expend serious effort to stop it.

What if the next Wii update patches the trucha bug?

It probably will. The only way to stop it would be to make sure the wii menu doesn't update itself. This would require a custom firmware update. A custom firmware update is risky at best to develop, as 1 mistake could brick your wii.

Wii Hacking

What's happening now?

A lot of people are working on fancy Wii homebrew. Lots of work remains to be done.

For example:

  • Building a working toolchain environment
  • Making a working low-level library to access hardware (CPU/GPU/controllers/USB/Framebuffers and debugging)
  • Documenting memory maps
  • Discovering usage of registers for (Audio Interface, Serial Interface, Memory Interface, Video Interface)
  • Triggering and setting up interrupt handling
  • Working on a stable Initial Program Loader
  • Reverse engineering IOS and other binary files

The Fish Disc looks really promising

The Fish Disc is able to transfer the bare essentials (savegames, preferences) of one Wii to another. It also allows all personal data to be erased, much like the "Format System Memory" option.

How can I boot homebrew on my Wii?

See the Twilight Hack.

What new features are you planning for the next release?

Hopefully, source code.

How did this happen?

The "tweezer" attack was originally used to access the restricted parts of the RAM. This allowed them to access/discover a exploit (as used in the original video)

This exploit can be patched "easily" by Nintendo and has as of IOS37. More information on the signing exploit can be found here or in this blog post by tmbinc.

There are a lot of keys, encryption methods, protection and systems in place.. Most of these are not public.

Can I use the Wii Remote in the homebrew applications?

A small number of homebrew supports the Wii Remote. See here for more information. You need to use a GameCube controller for most homebrew.

When will I be able to use the Wii's built-in front loading SD slot?

As of alpha3a of the Twilight Hack you can use a FAT16 formatted SD card in the front SD slot. Experimental FAT 32 support is added in alpha 3b.

This, however, does not mean applications support it. Most emulators still require access to roms on your SD-gecko, and the mp3 player as well.

Can i use GameCube homebrew on the Wii with a loader?

No, you can't.

Twilight Hack

How does the Twilight Hack work?

An exploit has been found in the Wii game "The Legend of Zelda: Twilight Princess". Once used it launches custom code. It is similar to the GTA PSP Exploit.

How do I use the Twilight Hack?

The Twilight Hack page has everything you need to know on how to use the exploit.

Is the Twilight Hack affected by the latest update?

Not as of yet and it may very well never be patched.

Homebrew channel

Where can I get the homebrew channel?

It is not ready yet, although an early version is available at the Homebrew_Channel page.

Does the homebrew channel do "X"?

It is not finished so features in a released version are unknown.

Can I request a feature for the homebrew channel?

Sure, but the devs may not like your idea. Requests can be made on the Homebrew Channel/Ideas page. Besides, they might already have decided if and when to implement "X".
