![]() The inclusion of “plug and play” or the ability to automatically detect a newly installed driver was pivotal at the time for device management and hardware support.Īs part of its grand ad campaign for Windows 95, Microsoft even used the star power of Jennifer Aniston and Matthew Perry in a 30-minute promotional video highlighting navigation in the OS. Promised to be the company’s most advanced iteration since its first 10 years ago the eventual Windows 95 is the operating system responsible for many modern conveniences end-users utilize today. It’s also the time when we saw the first season of the eventual hit show about six 20-somethings in New York called Friends.Īll the while, looming on the horizon is the speculated release of Microsoft’s new operating system, which was hinted upon earlier that year. ![]() Many are still reeling from Chicago Bulls guard Michael Jordan's decision to retire from basketball despite his first appearance on the baseball diamond that same year. Sure, it can’t compare to today’s standards of readily available mobile games, but at that time, it was an innovative piece of software.Īlthough most will probably associate the pinball game to the equally famous Windows XP, Space Cadet was bundled earlier, in Microsoft Plus!, the discounted commercial version of the Windows 95 operating system. and the decompiler has misinterpreted it as a longlong because of the access patterns (64bit pointers).A simple yet effective way to pass the time, Space Cadet provided many people their first experience playing a pinball game, both physically and virtually. So I think this might be part of an initialization function for some property on top of a object that exists at *param_1. ![]() The 0x2b part I'm not sure about myself but it looks like some other kind of similar checks.Īnd actually then thinking about the way it's calling it, i'm wondering if this is actually from some C++ standard library code for doing stuff with a vtable, looking up the vtable entry and checking it's validity before calling it (in this case, location 0x18, and checking some kind of RTTI at 0x28 and 0x2b) and storing that it's been initialized in 0x21. ![]() From my memory, the windows ABI uses the first two bytes of functions for installing hooks/debugging by patching the first two bytes into some kind of jump (while originally being nops). This particular one looks like it's taking a function pointer in and checking if it's a valid function (not null) and then checking the first two bytes of the function. The sibling comment covers it a bit more in detail, but it's largely just some guessing and as much an art to figuring out what the types are or could be. (disclosure: per the child post, my original assumption that OpenRCT2 was copied out of Hex-Rays was inaccurate, since it was originally written in assembler it didn't follow a standard C ABI and the decompiler wouldn't work properly anyway). ![]() For example, OpenRCT2 started as a repository full of manually created source with Hex-Rays names and slowly evolved module-by-module into readable source code. Highly manual process, for some files it's just pattern matching / renaming and goes really quickly, for others it's full reimplementation and a bit harder.Īnd, if you look at most "decompiled game" projects, I think this is the industry standard way to do this. When I've done this in the past, it basically consists of:ġ) Decompile project using Ghidra/IDA, first pass.Ģ) Load symbols if present (sounds like there was a PDB for this one, which makes things a lot easier).ģ) Read decompilation/asm for unnamed subs and try to name them based on what they do.Ĥ) Export all decompiled source into an editor and start copy/paste/editing into readable source. I'm not aware of any good general-case automation for this. ![]()
