Steve Corey has released a new version of Doom for the Nintendo Wii:
I fixed the bug that caused the shareware wad to crash in 0.4, so I'm releasing a version that includes only this fix. The homebrew browser can't put out the newest WiiDoom unless the shareware wad (which is packaged with it) works, so this was a high priority for me. Teknecal just confirmed that it's working, so he's putting it out in the next day or so.
