Version 0.6 of hell_hibou's Wii Homebrew Launcher was recently released, and you'll be pleased to note that there have been some changes that should make using it a lot better.

Here's a translation of hell_hibou's post on the Wii Homebrew Launcher website:

Following various bug appeared in version 0.5, I just put online version 0.6 of Wii Homebrew Launcher. The problems encountered in version 0.5 is due to mismanagement of memory, I implement a memory manager to manage and use the memory MEM2 of the Wii, leaving a maximum of conventional memory to load homebrews.

In addition, the library LIBOGC was last for days and benefit from the rapid initialization of the wiimote (more pressing need (1) + (2)).

Finally, it is possible to use the lever classic. The new version the ELF, DOL and WAD (string) is available in the Downloads section.

Feel free to download the application via the download link below. Just make sure you know what you're doing (in other words, translate the readme using an online translator) so you don't inadvertently do something horrendous to your Wii.
