If you can't understand it, just re-write it because I do not understand
what I was trying to do either.

I don't know where this array is, I think thats why I just came up with some
kind of hack.

It is possible to come up with a twos complement. Use this algorithm to
convert a 7-bit twos complement to an 8-bit twos complement:
if ((7bit & 0x40) > 0) // look for sign bit
{
7bit = (byte)(7bit | 0x80)
}

Don't remember...
