- Mask ROM by Macronix
Wii Mask ROM refers to a kind of ROM (read-only memory) whose contents are programmed by the IC manufacturer. In other words, it is not a user-programmable ROM. Since the process is costly, mask ROM is used when the needed volume is high and it is absolutely certain that the contents will not change.It is common practice to use UV-EPROM for the development phase of a project, and only after the code/data have been finalized is mask ROM ordered.The main advantage of mask ROM is its cost, since it is significantly cheaper than other kinds of ROM, but if an error in the data/code is found, the entire batch must be thrown away.
Wii / GC Disc Drive
The GameCube drive is also designed and manufactured by Matsushita Electric for use with the GameCube. The drive is unique in that it reads from the outside of the disc towards the middle. Some earlier and later revisions of the GameCube consoles did develop disc read problems with the optical pickup becoming thermal sensitive over time, causing read errors when the console reached normal operating temperature. Failures of this sort require replacement of the optical pickup. Affected consoles had sometimes been serviced free of charge by Nintendo even after the expiration of the warranty period.
A common misconception about the GameCube optical drive is that it spins the discs in reverse (counter-clockwise) from normal disc drives (which spin clockwise). The peculiarity of this rumor is that one need only open the disc tray on an operating GameCube to see that the disc clearly spins clockwise as it slows to a halt.
Why You need a Wii Mod-Chip:
- Play all reagion DVD movies on your Wii Console
- Launch copied / backup GameCube mini DVDs
- Play free roms on Wii Virtual Console
- Use unlicensed homebrew applications and games
The Nintendo GameCube Optical Disc is the media format used by the Nintendo GameCube and Nintendo Wii. The disc is a proprietary version of the eight centimeter DVD (MiniDVD) format. The capacity of the disc is 1.5 GB. Some games which contain large amounts of voice acting or pre-rendered video (for example, Tales of Symphonia) have been released on two discs; however, fewer than two dozen titles have been released on two discs, and no games have required a third disc. Manufactured by Matsushita, parent company of Panasonic.
Nintendo has stated that the Wii will be backward compatible with all GameCube software and most peripherals. This backwards compatibility is achieved through a set of ports on top of the console concealed by a panel. There are four GCN controller ports and two GCN memory card slots as there were on the GameCube itself, so the GameCube microphone should be compatible, as well as the DK Bongos and the GameCube-Game Boy Advance cable. There is no indication that the Wii has the high-speed port of the original GameCube, which means that unless otherwise indicated, the Game Boy Player (which required this port) will not be compatible with the Wii.
Nintendo Wii Mod Chips
Current Progress: The GameCube part of the Wii has been hacked - you can load unsigned code - DOL files using Action Replay CD + SD Loader. Wii side of the console will a lot harder to hack to do to constant updates from Nintendo.
Contrary to popular belief Nintendo Wii uses standard DVDs with a modified file system for game storage. Nintendo Wii modchip called Viper was released in December of 2006. There is a moded hacked BIOS available for the Viper called Cobra that allows the user to directly boot a back-up or homebrew game on a 3-inch DVD-R inserted in the Nintendo Wii's optical drive . Like most console mod-chips, it attempts to avoid legal complications by including no code which circumvents copy protection or is copyrighted by Nintendo. It has some on-board flash memory which allows the user to write small programs to it (.DOLs). Removing the Nintendo Wii's external case or installing a custom replacement allows the user to boot standard 5-inch DVD-R discs as well, but the positioning of the drive's laser renders only the first 1.4GB of capacity usable. Previously the only common way to run user code on the Nintendo Wii was to use a LAN Adapter combined with a security hole in Phantasy Star Online. More recent (v1.0+) versions of Cobra no longer require an original disc for authentication purposes. TMBinc released an open source IPL replacement for NGC, which allow anyone to produce is own IPL replacement (modchip for NGC). The Cobra software works, after an original disc is authenticated, by resetting the disc drive and unlocking a debug mode which allows code to be sent to the drive and executed. This code stops the disc drive for a few seconds, allowing the user to swap in a non-original disc. Alternatively, the DuoWii and XenoWii are available. They don't have the features of the Viper, but do allow booting of homebrew programs such as SNES and burnt games.
Alternatives to Modchips
Mod chips are not entirely necessary if you wish to try a different approach, such as WiiLoader, HD Advance and/or Wii Independence Exploit, because it allows the user to install a hard drive, and copy the contents of original game DVD discs to this hard drive. At this point you no longer require the original DVD or even a modchip to play the games from the hard drive installed into the Wii. By using M.R. Browns Wii Independence Exploit, one can store the HD Loader executable (or any other homebrew code) on the memory card, trigger the exploit and load the copied games without using a burned disc.
