I am a person interested of old games (MS DOS and 16 bit Windows only) and programming. In 2020, I saw an article about hacking SkiFree somewhere on the internet and soon as I followed the instructions, it was so easy that I made many games with changed graphics and added sound effects (the later 32 bit executable has a hidden ability to do so). Later I tried to go to different lengths after being impressed with my previous stuff mentioned above. Like adding new objects (referred as things in the code). I have explored the original executable using a hex editor and found this:
I have heard of old Windows applications being leaked by hackers, causing mass controversy and a big problem for Microsoft. They say they extracted the c files and headers from the executable file. Sometimes without a decompiler. I have been working on a SkiFree project for nearly 3 years only for my own enjoyment and I want to know which software do they use to do this. Can anyone help me?
