D2Ckey總結整理

總結： (不想看詳細的資料朋友看這裡就好)
D2Ckey和wiikey的功能幾乎一樣(都是直讀全區)，不過多了D2C支持。
為了D2C的保護方法，所以新的D2Ckey多了非常多的線來偵測光碟機訊號，
因此和wiikey比較起來多了一個發光指示功能(原版片和備份片有不一樣的發光指示)。
當然D2Ckey也號稱比Wiikey更不易被(Wii偵測而)鎖機，
不過反正Wiikey也沒有被鎖機....看看就好

本文純翻譯而且技術文字看不太懂(我不是電子/電機人)，有錯誤請指正。
另外在沒看到實際東西前一切都是夢幻泡影....(更不用說D2Ckey Clone)
雖然wiikey小組在wiikey首發時宣稱的目標都有達成，
只不過時間晚了半年....這次不知道會Lag多久 XD
and...不負責猜測，看圖D2Ckey是修改Wii的光碟機系統晶片，
不是Wii主機系統，所以應該是不能解磚....

It Just Work
可用
Direct boot of Wii and Gamecube games, on-the-fly region patching, audiostreaming fix and
more.
直讀Wii和GC遊戲，直接區碼修正，(GC)聲音流修正和更多。

D2CKey has been designed with user simplicity in mind. After installation (which, in all fairness,
should be left to a professional!), it just works. There is no need to set up, reflash, upgrade, or fiddle
around. D2Ckey automatically detects what kind of disc is inserted, and configures the drive
accordingly. Original and backup original Wii and Gamecube games from different regions with the
same video system boots directly, and even a lot of games from regions with different video system
can be booted directly. Gamecube audiostreaming fix is built-in from the start.
D2CKey在安裝後(安裝留給專業人士)是簡單易用的設計，不需要設定、更新、升
級就可以
用。D2Ckey可自動偵測放入的光碟，然後根據放入的光碟來設定光碟機。(不同區但相同影
像系統)日版與美版的Wii和GC遊戲可以在日、美機直讀，即使是不同影像系統(指歐的PAL
和美日的NTSC不同)的很多遊戲也可以直讀。內建GC聲音流修正。

Use with all kinds of media
支援所有的光碟
Compatible with most DVD+/-R and RW media (no bitsetting required) and multigame discs.
支援大部分DVD+/-R和RW光碟(不需要bitsetting)和多光碟遊戲

DVD-R, DVD+R, DVD-RW, Dual Layer DVD, bitsetting... finding the right recordable media and the
right burner isnt always that easy. Some kinds and brands of media and recorders might work better
with the Wii drive than others. D2Ckey offers support for most of them from the start, making it
simpler for you. While a certain media, burner, or combination might not work properly with a
certain drive, it will be easier to find a working combination knowing that d2ckey supports most of
the common recordable media types.
DVD-R, DVD+R, DVD-RW, 雙層DVD, bitsetting...找到好的光碟片和好的燒錄機不
容易，有些
光碟片和燒錄機對Wii的支援比較好。D2CKey支援大部分的光碟片和燒錄機。

Hottest Chip/Coolest Core
超熱門晶片/超涼快核心
350MHz Performance with advanced AES128 bit encryption, yet runs on an ultra-low-power core.
AES128bit進階加密的350MHz執行效能，可以在超低電壓下使用的核心。

The overall system performance of D2Ckey is 350Mhz, compared to around 8MHz for serial-port
based modchips.D2Ckey uses the latest flash-based FPGA technology from Actel, which has many
powerful features. It has a super-fast, ultra-low-power 1.5V core that will literally remain cool all the
time. This means no strain on your Wii (and there is no need recalculate your carbon
footprint).Another powerful feature is that the programming is protected by powerful AES128
encryption, making reverse engineering attempts infeasible. Therefore it will be very difficult to find
a way to detect or block the chip in any way in the future. In the past modchips and smartcards using
less secure devices have eventually been hacked, making it possible to detect them and lock out
modified systems. An example of this are self-updating d2mac and Conax satellite tv pirate cards,
whose MK's have been revoked, rendering the card inoperable.
D2Ckey的整體系統效能是350MHz，其他serial-port(序列埠)的改機晶片是大概
8MHz。
D2Ckey使用最新的FPGA技術提供了許多超強的特色：超快、超低電壓(1.5V核心電壓)讓該
心保持涼快，讓你的Wii不增加負擔(不會增加用電量)
另一個超強特色是使用超強的AES128加密，讓逆向工程(Clone啦)幾乎不可能，所以很難偵
測或封鎖晶片。以前的晶片和智慧卡沒有使用安全設備所以會被破解，甚至可能會被偵測和
封機。舉例來說像可自動升級的d2mac和Conax衛星電視盜版卡(這是什麼?)被MK's封了。

Intellignet code modifying system
智慧碼修正系統
Integrates a next-generation ICMS to ensure stability during loading and gameplay.
整合次世代的ICMS保證遊戲穩定度。

The first generations of Wii drive controllers - known as DMS, identical to D2A, and D2B all had a
serial port interface that could be used to inject code, making it possible for backup discs to load (and
enable other funky stuff as well).Albeit easy to install, modchips that uses the serial port have some
disadvantages. Due to the way they interact with the drive controller it is possible for the Wii
hardware to detect them (they modify RAM, for eample).This way of modifying the Wii does not
work with the D2C controller, because the serial port can no longer be used to inject or modify
code.D2Ckey uses a new approach we call the Intelligent Code Modifying System (ICMS). Instead of
just uploading some code and then doze off, ICMS constantly monitors data on address and data
buses, patching it if necessary. This has several advantages:
1.is virtually undetectable by the Wii hardware
2.Improved reading of recordable recordable media
3.Backup disc loading will emulate original game disc loading closer
By interfacing more of the circuitry of the drive controller D2Ckey has a better understanding of what
is going on inside. Stability and compability have been the main design objectives.A good example
of the dangers with oversimplified chips are the 4-wire PIC12C508-based PS1 modchips that where
very popular around 1997. First, Microchip, the manufacturer of PIC chips, made some changes in
the manufacturing process, affecting the in-system clock. This was technically not a manufacturing
flaw, as the fault was still within the tolerance specified in the datasheet, but the chips stopped
working. If the 5th wire, a clock signal from PS1, had not been stripped (the 5-wire modchips still
using the PS1 clock did not have any problems) then there would not have been any problems.
Shortly after games appeared that detected active modchips - once again, a few extra wires would
have enabled the chip to know when (and when not to) send data.
第一代的Wii光碟機控制系統(DMS/D2A/D2B)有serial port (序列埠)介面可以用來寫
入指令碼讓
備份片可以直讀(和其他有趣的用途)雖然安裝簡單但是serial port (序列埠)晶片有一些缺點，
由於和光碟機系統的互相影響讓Wii主機可以偵測到，因為他們修改RAM。這個修改Wii的方
法在D2C系統上不適用，因為iserial port (序列埠)不能用來寫入指令碼了。
D2Ckey使用我們叫智慧碼修正系統(ICMS)的新方法，以前的方法是載入一些修正碼然後就
不做事了，而ICMS會不斷偵測資料並在需要的時候修正，這方法有一些優點：
1.完全不可能被Wii主機偵測
2.改正燒錄片的讀取
3.備份片載入像正版片一樣
藉由和光碟機更多的交流讓D2Ckey可以更好的瞭解狀況，穩定度和相容性是主要設計目標。
一個好的例子是在約1997年PS1過於簡單的晶片是4線PIC12C508發生的危機，首先是PIC晶片
的製造商Microchip做了些製程變動影響系統時鐘，技術上來說這不是製造流程缺點，這個失
誤仍在規格容忍範圍內，但是卻造成晶片失效。如果第5條線(PS1的時鐘訊號)沒有被拆卸(五
線晶片仍然使用PS1時鐘是沒有任何問題)就沒有任何問題。簡短的來說在遊戲再一次偵測到
改機晶片，就需要啟用額外的線來讓晶片知道何時要送資料(和何時不送)。
