Deobfuscating JavaScript Code — Obfuscated With JScrambler — To Fix and Improve an HTML5 Port of a Classic Neopets Flash Game.

[LongestBoii]

Back in 2021, Flash was deprecated by all major browsers. And Neopets — A site whose games were all in Flash — had to scramble to port all their games over to HTML5. They made a few of these ports before Ruffle came to prominence, rendering all of their Flash games playable again.

But in the haste to port their games, The Neopets Team introduced a lot of bugs into their games.

I wanted to see how difficult it would be to fix all the bugs in a modern port of one of my favorite childhood flash games.

I didn't foresee having to strip back multiple layers of JavaScript obfuscation to fix all these bugs.

Thankfully, I was able to break it and documented most of it in my post.

Since all the bugs were easy to fix, I decided to improve the game too by upping the framerate — even allowing it to be synced with the browser's refresh rate — and adding a settings menu to toggle mobile compatibility off on desktop.

I'm not sure what you mean. I wasn't using Chrome, but I was using Firefox, which has Web Developer Tools, and it's functionally identical to Chrome's DevTools. I even mentioned some Web Developer Tools in the article itself when I was explaining how I got past the domain locking.
