Hacking Problem: Some homebrew works, some (and VC) don't.

[surusumi]

Hi everyone, it seems that some homebrew just won't run for me, just as the VC games I tried.

I am on a 3.2J install, I have the hbc installed and some homebrew works (ftpii 0.0.15 for example), but others don't (ftpii 0.0.17 or Snes9x). When I start the them I only get a black screen and most of the times the wiimote shuts down. I can not do anything at this point except shut down the wii and restart. The same for the VC games I tried.

I think I might need some IOS, but I have no idea which this could be. I was on firmware 4.0 and the problem was exactly the same.

Any help would be appreciated!
