I'm not sure if I'm supposed to reply to my own question, but I figured I'd
share some progress in case someone can give me an idea to go from here. I
changed the image to grayscale and then used win32api to get the color of
the pixels in the words (probably should've just used paint.net). I've seen
people say it does better with black text on white backgrounds so I made a
function that checks each pixel to see if it's within a tolerance of the
value I got for the words, this is because the words seem to have a weird
8-bit bevel effect so the pixels are lighter in the center of symbols and
darker towards the sides. When a pixel fell in the tolerance I changed it's
value to pure black, and all pixels than didn't were changed to white. I
also scaled the image size up to 4x it's original size. Which helped with
the reading a bit.
The results of the Tesseract scan were:

A worry I have now is that the "Tolerance" I had was 65! Grayscale only has
an intensity value between 0 and 255 as I understand it. So in order to get
the words to show up I needed to look for pixels in a range of 130 just
over half the intensity spectrum. If I were to move from this to a more
busy screen that had sprites on it I'd imagine a bunch of pixels would be
turned black while trying to get the writing to clear up and separating the
actual text reading from the noisy garbage you get trying to read a black
splotch is going to be hard. Is there any way to do this?
