![]() NOTE: It is not important if the second checksum (for the data) since it has been downloaded to RAM anyway, seems ARGON/D2Pro uses checksum = 0 The DVD controller then expects to receive length bytes of data followed by an eight bit checksum The Secret Key is located at 0x80800 in the DVD controllers memory, if it is set to FFFFFFFFFFFFFFFF in the DVD controllers memory then no check is madeĢ0, KK, KK, KK, KK, KK, KK, KK, KK, 00, 00, CCĭownloads data to the DVD controller's RAMģ0, 00, PP, PP, PP, LL, LL, 00, 00, 00, 00, CC This is the first command to be sent and enables all the others. The modchip sends commands (and optionally data) to the drive controller which responds with its statusĬC is the 8 bit checksum (add first 11 bytes modulo 256) Here is a description of the "Serial Writer" protocol commands used by most modchips. A clock glitch allowed mod chip vendors to defeat this protection and use the "Serial Writer" to inject firmware. It looks as though Matsushita tried to disable this interface in the D2C and newer drive controllers. ![]() This is the interface used by 9 & 6 wire mod chips to patch the drives firmware. It also seems to be impossible to send that password from code running on the Wii, but perhaps is possible to directly send it over the ribbon cable. The password used to unlock debug mode was changed from "MATSHITA DVD-GAME" to "matshita dvd-game". ![]() The MN102 chip accessed via Hardware/DI is backwards compatible with the one on the GameCube, but has additional commands see /dev/di for examples. After removing these screws, unplug the disc drive and gently remove the ribbon cable. Gentle means gentle, so it is not recommended to go any harder then it should be.ĭust buildup can happen at the rod section inside the drive, which can be cleaned out with a q-tip.Īssuming that the disc drive needs to be totally replaced, there are about three or four screws (depends on model) holding in the drive. This can be done by using a q-tip and isopropyl alcohol, and gently cleaning the lens using the q-tip. If the disc drive is incapable of reading discs well, it is recommended to clean the lens. Inside the disc drive, the most likely component to fail or to wither in performance is the lens. The Wii disc drive is the most likely component to fail in the Wii due to aging and moving parts.
