So people here use a program to detect what font it is? or do they know by recognition, knowledge and memory. Maybe I'm asking for a custom font specifically made for Sonic Mania.

Looks like they used the website wordle.

The font you are trying to find doesn't have to be pixelised like the one shown. It just has to look like this when viewing in a lower resolution.

This screenshot comes from the Sonic Mania Trailer.

You are asking a lot of fonts that come from porn sites (judging by the text they contain).

What are the two fonts that say "GREEN HILL" and "ZONE". I guessing that they were originally more detailed and were pixelised for the sake of the game it came from.
