Unlike earlier drives, on which the PCB could be easily swapped with one containing a different chipset (D3 - Nintendo also continues to employ anti-piracy methods on their games.
New Super Mario Bros Wii, for example, will not play out of the box because the game checks the burst cutting area for data not normally in a rip.
Disc read speed is limited to 3x (compared to 6x for normal games), which leads to many games having video playback stutters and slightly longer load times.
A disc drive chipset called the D3 introduced a radical change, as the chip the drivechip clipped to was no longer on the PCB.
Drivechip manufacturers chose to use a dongle method to trick the drive to use its built-in DVD mode, which was meant for a potential DVD player on the Wii.
Although it is frequently called solderless modding, this is technically incorrect since soldering will still be required.
The number and location of solder points on the drive chip is "automatically" accounted for through the use of chip-clips, and such clips extend the range of future possible solutions.
Such chips are advertised as "plug and play" and include the Flat Mod, Flat Mii, Wasabi DX, Wii Key Fusion, Drive Key, and the WODE Jukebox.
There have been reports of bricking (rendering the unit inoperable due to an incompatible firmware update) of a small number of Wii consoles after the installation of an update to System Menu 3.0, Due to hardware revisions, older drivechips may not work on newer Wii systems.
As a result, they are often referred to as drivechips.
Most modchips are capable of circumventing region coding and copy protection, which allows users to play games created in different regions, load burned discs, and use third-party homebrew software.
Many vendors now presolder the chip to the clip, making it a true solderless kit.
