![]() ![]() and the decompiler has misinterpreted it as a longlong because of the access patterns (64bit pointers). 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. Bateu a nostalgia do Space Cadet - 3D Jogue agora mesmo em seu Windows XP, 7, 8, 8.1 ou 10 sem mesmo precisar de instalar em seu computador.Tudo isso de g. (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. 2016 Licence Free OS Support Windows Downloads Total: 802,546 Last week: 110 Ranking 4 in Arcade Publisher Microsoft. 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. Microsoft Windows Pinbal, or 3D Space Cadet Pinball was introduced in Microsoft Plus 95, it then became so popular that it was included in Microsoft Windows NT 4 by default. I'm not aware of any good general-case automation for this. Original-Sounds aus dem Spiel '3D Pinball - Space Cadet' (ein Flipperspiel für Microsoft), 1995 programmiert bzw. ![]()
