Unstable, improvised to works on Win 7/8.
Portable version eats more than 6 GB of RAM. Brave-portable.exe already includes --no-sandbox flag.
Run with !NoSandbox.bat instead on Brave.exe (non-portable version).
Changes from Brave 1.58.129 are in https://gist.github.com/adeii/d168ead8a4cac9af3a481b7d5da00527
