    Hello, first time poster here.
    I'm currently trying to build a versatile media center inside my original NES case to launch whatever SSD equipped NES Catridge I have. That part seems fairly easy to me. The modification of the circuitry on the other hand is [almost] completely unknown to me. I know how to weld but recognizing what goes where is really hard.

    You can look at what I'm talking about on this imgur link.
    1- Brown
    2- Red
    3- Orange
    4- Yellow
    5- White

    I want to keep the board as is, but cut the cords and weld them on a raspberry pi or others to:
    - Power on the machine
    - Have the led from the board indicate when it's on instead of the one on the board
    - Find a function for the 'Reset' button

    My questions are:
    - How can I determine which cable correspond to what ?
    - If I make a association mistake and test it powering on, can I damage the components I'm working on ?


    EDIT: I figured this isn't really an assignment, but I also want to learn how to figure it to be able to replace it in case something stop working in the future.

    A simple continuity tester or mutimeter is required.
    Check continuity of each wire to each switch position.
