Drivechip Detection

There's a very popular myth concerning the current Wii drivechips: many people believe that it's technically impossible for Nintendo to detect them. People who believe this will usually mention reasons like "they don't even modify the Wii or the DVD-Drive-Firmware, so they can't be detected!". The fact that the Wii drivechip makers solicit their products with buzzwords like "Stealth" supports this myth as well.

But fact is: At the latest when you're running a backup disc, ALL the current Wii drivechips can theoretically be detected. In fact, it would be quite easy for Nintendo to do so.

All current Wii drivechips work by connecting to an unused serial debug port of the DVD drive controller (that's that DMS/D2A/D2B thingy you've heard of). This debug port can for example be used to read/write the RAM used by the DVD controller, and that's exactly what the current drivechips do: To make backup discs work, these drivechips must modify the DVD controller RAM in some way. Now what makes the drivechips detectable is that the Wii can read/write that RAM too (in fact even gamecube software can do that - just remember how GCOS can read your DVD drive date/version, or how gamecube homebrew discs can be used to update the drivechip firmware), so it can check for any unusual changes in the DVD controller RAM that can only be caused by a drivechip. Maybe the easiest way of doing so would be to check a special memory location that unlocks the DVD controller memory. About the first thing ALL current drivechips need to do to get backups running is to write the value 0x41 to that memory location. Check the source of dvdtool or any open source modchip you like and you'll see that it's true. Periodically checking that special memory location for that special value would be enough for Nintendo to detect all current drivechips. There would be no way of tricking that mechanism in order to get backups running. And so what ? This IS the value the wii firmware MUST read when an original game is inserted, else it won't play. In my opinion, it isn't a way for nintendo to detect a modchip.

Starting with Wii firmware version 3.0, firmware updates are accompanied with a warning message that the update might "cause inoperability" if the Wii has an "unauthorized technical modification". Chances are this message just appears to warn owners of modded Wiis about the risk of bricking their console when running a different-region game that tries to install a different region firmware update. But with Wii drivechips being out for six months now, the risk that a new firmware update is indeed capable of detecting drivechips is growing and growing; if Nintendo really wants to fight modchips, they should have been able to develop effective strategies by now - the example above shows how easy it would be. And remember, a newly released firmware update that doesn't seem to affect modchips can be deceptive; remember how Microsoft waited for months before they banned owners of modded 360s.

So if you think about updating the Wii firmware to versions >= 3.0, remember that there always remains a chance that they are not really mod-safe.

А чип изменяет в памяти ДВД привода только информацию о том, что он читает болванку. Хорошо, Вии тоже будет читать память ДВД привода. И что она там увидит? Информацию о том, что в приводе стоит лицензионный диск! В этом и заклычается задача чипов - подменять эту информацию для Wii, иначе они не нужны. Другое дело, если какие-то чипы делают это не совсем корректно, тогда да. Но если это обнаружится, это исправит первое же обновление чипа.

Или я что-то не так понимаю?
