There are a total of nine ranks in the game, from Cadet to Fleet Admiral. As you earn points, your cadet will be promoted to the next rank, making new missions available. GameplayģD Pinball: Space Cadet is a video pinball game with pseudo-3D graphics and an emphasis on progression through completion of missions. This process was later discontinued beginning with Windows Vista. It was later included in multiple Windows releases (along with other games, namely Solitaire, Minesweeper, FreeCell, and Hearts), where it gained in popularity. The table is presented in a skewed pseudo-3D perspective (with a pre-rendered table and a dynamically-resizing 2D pinball) and has some differences with the Full Tilt version (such as the lack of extra balls and multiball rounds). In it, players play as a starfleet cadet as they complete missions to get promotions (from Ensign to Fleet Admiral). The game only includes one table: the sci-fi themed "Space Cadet". It was later included with most installations of the Microsoft Windows operating systems from Windows NT 4.0 to Windows XP.ĭeveloped as part of the Microsoft Plus! for Windows 95 expansion disc (which was released in-tandem with the Windows 95 operating system), 3D Pinball for Windows is a special pre-release version of the Maxis game Full Tilt! Pinball, released months later. and the decompiler has misinterpreted it as a longlong because of the access patterns (64bit pointers).Overview A standard game of 3D Pinball for Windows, running on Windows 98.ģD Pinball for Windows - Space Cadet (also known as Microsoft 3D Pinball for Windows - Space Cadet, 3D Pinball: Space Cadet, 3D Pinball, and Pinball) is a sci-fi video pinball game developed by Cinematronics and released by Microsoft for Windows PCs on August 1995 as part of the Microsoft Plus! for Windows 95 package. 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.
