Author here - there are better emulators (I used this one myself for testing things out: https://www.retrodevops.com/c64.html https://www.retrodevops.com/c64.html). You are absolutely right that my POKE is not like the real one - because for that, you actually need to emulate quite accurately the C64 memory. So, anything related to POKE is not accurate - and this misses the experience you get as a hacker discovering tricks you can do. However, my point was more about the interaction that combines text editor and REPL into one - and I think for that, it works well enough.
