    Why Revisions Matter
    Nintendo made several changes to the Wii throughout its 7 year life cycle, presumably to reduce price, reduce unit failure rate, and replace discontinued parts. However the biggest change was when they performed a die shrink of the GPU. This resulted in a HUGE reduction in power consumption and heat generation. When redesigning for these new chips, Nintendo also reduced the number of circuit board layers from 6 to 4. For trimming purposes, revisions can be sorted into 2 categories: 4 Layer boards and 6 Layer boards. Each type has its own advantages and disadvantages. Here is a general overview:

    6 Layer boards:
    - Consume much more power
    - Create much more heat
    + Are more common: easier to find
    + Easier for newcomers to portablizing
    4 Layer boards:
    - Consume much less power
    - Create much less heat
    + Are less common: easier to spot
    + Requires a bit more soldering finesse

    NOTE: All Wii revisions support GameCube controllers.

    Overall, a 4 layer Wii board will consume about half the power of a 6 layer board. This will result in a portable with much better battery life. A 4 layer board will generate less heat, so it will run much cooler. However, a 4 layer board requires 2 very difficult soldering connections. While a 4 layer is better overall, a 6 layer is easier to work with.

    How to Identify the Revision of a Wii
    1: Identification based off of shell.
    Nintendo didn't release Wiis in colors other than white or Wiis without GameCube ports until after they switched to the newer die-shrunk chips on 4 layer boards. This information is very useful for tracking down a 4 layer board. However, it is less reliable for determining if a board is 6 layer, so methods 2 and 3 are preferred.

    2: Removing the battery tray
    By unscrewing a single phillips screw, you can figure out the exact revision of a Wii without completely dissembling it. Inside is a 2-3 digit code silkscreened onto the motherboard. See the table below to match the code with a revision.

    3: Complete Disassembly
    By completely disassembling the console, the revision is clearly visible in the location circled below.
