The Super Paper Mario thing screwed the guy's system because he tried installed PAL firmware on an NTSC console, or visa-versa, it wasn't some trick by Nintendo to brick modded systems, and it had absolutely nothing to do with the modchip inside it, other than the fact that it allowed him to boot said game. Wii modchips only hack the drive code, which can't be read by the Wii OS, and is the reason why you can only load Gamecube homebrew and not Wii homebrew. There were tons of modchips for the Gamecube near the end of it's life (which was some time in 2004). I'm not condoning the use of modchips for playing illegal backups of games that you do not own, but I'm all for using them to play homebrew, such as many of the emulators for Gamecube which you can now play on Wii, or GC Linux. Also, Nintendo is not legally allowed to brick your console because it has a chip (even though there's no way they could even know you had one, at least not the type of modchips that are out now), all they can do is void your warranty and refuse to fix your system if you modded it. What's kind of funny though, is Microsoft will fix your firmware modded XBox 360 (for free), as long as it's under the 1 year warranty time period, they did this for a friend of mine, whose 360 I modded.
