As DOSBox Staging is a volunteer effort, we are not in a position to make such payments. To prevent this, developers are expected to pay Microsoft’s EV certification vendors a yearly fee and put the software on Windows Store. So, I was more focus on protection, not virii things. Starting in Windows 8, Microsoft Defender SmartScreen’s pop-up encumbers the execution of newly-developed applications. I coded a simple protector called FSE at that time as well. Change into the project directory then run make -j4 to build it. To build under linux, make sure GCC 9 (package g++-9) and GNU Make (package make) are installed. You can start DOSBox-X without any option, or with any of the following options. ROSE (Ralph Roth) and Stone (The UCF one?) are my friends in DOS time. Open dosboxpurelibretro.sln in Visual Studio (all versions from 2012 and up are supported) and press build to build the dosboxpurelibretro.dll core file. It were good times, I think I keep collecting DOS stuff for my collection because I learned all through these things (and not coding stupid crud Clipper vertical programs ) It were good times, I think I keep collecting DOS stuff for my collection because I learned all through these things (and not coding stupid crud Clipper vertical programs. Maybe many of you remember coming to this same page to get last versions of Unp unpacker, or the many packers released by ROSE, Stone, etc It was a very prolific time, maybe people coded packers and protectors, other people created specific deprotectors or even better, generic unpackers, using VMs a a lot of advanced stuff. My favourite stuff to research were mutation engines, cryptors, tracers, etc The debugger built-in to DOSBOX is easy: it has a side-channel to access the entire machine state. Under DOS, the debugger has to insert itself into a different region of memory than the program being debugged. Under a multitasking OS, there are system calls like Linux ptrace that can manipulate the state of another process. Btw, I maintain a huge DOS virii collection, also a DOS CRACKMEs collection, all those are extensively search online and scrapped and collected for any site I've could found (if you have stuff to add, make me happy and send me links ) The debugger built-in to DOSBOX is easy: it has a side-channel to access the entire machine state. I recommed you guys download some online collection or repo of virii zines ,still many things online, get it before is impossible to get. The HPVA scene was a incredible learning resource for many people, I specially remember many Virii zines as A29, 40hex or Vlad magazines. With these people you learn to think as a reverser, yes you do specific things, but you learnt how these guys solved complex problems in optimum ways, many time hackish, but sooo much fun, and also usable in modern times in many different problems. Vecna also produced very good code, but Z0mbie used to released weird and interesting stuff (as the zip cryptor he used in his Still today reading all the stuff released by z0mbie would be sooo useful for many people,
