D2CKey modchip for Wii with D2C chipsets

[bandit]

I'm a little late on posting this as I wasnt sure if this was a fake or not but I just got word that D2Ckey is from the team behind WiiKey.

D2Ckey is the first modchip to work on D2C chipsets on Wii's. Previous modchips did not work on newer Wii's. It requires 31 wires and 2 jumps to be soldered. NEOASIC has found an alternative solder points. You can take a look at the installation here.

Technical Specifications:
Access control LEDs

• LED 1: disc access indicator.
• LED 2: data patching indicator
  
  • Flashes smoothly during disc insertion and detection
  • Lit when backup is detected (after disclogin)
  • Off when original is detected

DVD media compability

• DVD+-R
• DVD+-RW
• Dual-layer DVD (movies and GCOS)

Game disc support

• Direct boot of Wii original and backup games from the same region
• Direct boot of Gamecube original and backup games from the same region
• Direct boot of different NTSC region Wii and GC games on USA and JAP consoles
• Partial region free support on Wii and GC original and backup games with different videomode (ie PAL<->USA, JAPAN)
• Improved readsettings for recordable media
• Supports running GC games at Wii diskspeed
• GC Audiostreaming Fix
• Supports full-size DVD and DVD9 discs for GC homebrew
• Supports GC multigame discs
• Supports Wii and GC multidisc games

True stealth mode

• Does not modify RAM, making it virtually undetectable for the Wii
• Full command set emulation

It Works
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.

Use With All Kinds of Media
Compatible with most DVD+/-R and RW media (no bitsetting required) and multigame discs.

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.

Hottest Chip / Coolest Core
350MHz Performance with advanced AES128 bit encryption, yet runs on an ultra-low-power core.

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 unofficial satellite tv cards, whose MK's have been revoked, rendering the card inoperable.

Intelligent Code Modifying System
Integrates a next-generation ICMS to ensure stability during loading and gameplay.

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 example).

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:

• It is virtually undetectable by the Wii hardware
• Improved reading of recordable recordable media
• 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.

They currently have an installation guide available.

looks like one hard install, i think mine was only about 6 wires
