ELI5: How cassette games work

How do old video game consoles use cassettes as games when cassettes are just audio?
gpt
The data was represented as audio on the tape. When loading a program from tape the computer would listen to the noises - usually lots of screeching - and understand them as the bytes of the program which it could then run from its memory.

We used to use a similar technique to access the intent using a normal phone line - your computer would call another computer and they would screech at each other to send data back and forth.

So yes tapes are just audio but you can represent computer code as audio!
