/*
    Redirects page based on input from user.
    Input:
        - System version
        - O3DS/N3DS

    General exploits are as follows:
    - 1.0 - 11.3
        - Soundhax, compatible in all regions, all models
    - 11.4 - 11.13 with matching NVer for each version (and some KOR quirk):
        - SSLoth-Browser, doesn't work on cart-updated FW
    - O3DS & 11.4 - 11.14 & any cart-updated FW between said version:
        - safecerthax, compatible in all regions, O3DS only
        - This way O3DS still gets an easy way to install something if browser isn't functional
    - N3DS & 11.14 - 11.15 (EUR / JPN / USA) 
        - Update and do 11.17 guide
    - O3DS & 11.15:
        - Mii mine
    - 11.16:
        - Seedminer
    - N3DS & 11.17 (EUR / JPN / USA):
        - super-skaterhax
    - O3DS & 11.17:
        - Use alternate exploits; can't hack without any extra stuff
