I've reverse engineered a number of content encryption schemes. It's always a ton of fun, and you get to see the large amount of psychological warfare at play at the higher tiers. A very common trick that I've seen in a lot of Japanese games, for offline material, is to combine a hashing system and encryption. That is, the game will attempt to load "main.script", which is a custom bytecode scripting language. The fil…
What is the backstory behind why the company stopped selling this software? Has anyone asked the author or company about it? Would it be worth asking them to release the source since it's been so long since selling it?
Wollay and most software development he does is intermittent at best. The Cube World community went 6 years without an update. He will occasionally (every few years) post screenshots and teasers on social media, but it seems very clear that development of his projects is whimsical. I don't think anyone at this point would be surprised if he tweeted out tomorrow that he's done developing Cube World. It also seems that…

Which parts are the coroutines?

Animate(image);

At this point he can't bring it back. The article author bought the expired domain and put up his own authentication server on it.

> It's not pretty, but this is probably the first time anyone's been able to use Plasma at all in the better part of a decade. It seems that Wollay removed a critical UI file (for the sheet which artwork exists on) from Plasma, and made it so that the server would provide an obfuscated version of it to the client. That way, no amount of tampering could get an unauthorized copy of Plasma to work. Unfortunately, without the authentication server, authorized copies of Plasma cannot work anyway.
Around this time, I started looking at what the picroma.de domain used to point to. I didn't find much of interest on archive.org, but...
The domain was now available after all these years, and I bought it.
To clarify, none of the reverse engineering stuff is the issue. However, when your start reimplementing or circumventing "authorization", then you're potentially in some trouble. Worse, it's not civil, like copyright infringement, whereby the IP owner has to go after you. It's criminal, so technically law enforcement themselves can go after you.
In this case it seems unlikely, still though, be careful, folks.

What kind of games are we talking about? Computer games or mobile ones?

Indeed, it's often more fun than playing the game itself; but then again, I'm someone who has been taking things apart since I was very young (and not surprisingly, got into trouble a few times for it...) I suspect RE is something that's closer to what those in the other sciences do, i.e. analysis and thinking more about how/why things are the way they are, rather than what they can build; which is why not a lot of d…
This is part of a larger pattern of fairly weak attempts to confuse a reverse engineer that made it frustrating to figure out what all the opcodes did, and there were many duplicate opcodes that were just implemented in different ways. Since the code presented in the article didn't look like handwritten Asm (and if it was, it would've probably been even more insanely obfuscated and greatly confused IDA's decompilatio…
Pure speculation, but it's quite possible that it was written in Delphi (the last iteration of Borland's Turbo Pascal lineage), which had a fast single-pass compiler that did very little optimization. Delphi was very popular in Germany in the late 1990s and early 2000s.
