![]() ![]() Press the ‘Z’ and ‘/’ keys on your keyboard to control the left and right flippers. Then release the space bar to release the ball. ![]() and the decompiler has misinterpreted it as a longlong because of the access patterns (64bit pointers). Press and hold the space bar on your keyboard to pull the plunger back. 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). The primary goal of the Space Cadet 3D Pinball game is to launch the ball and then earn as many points as possible by hitting bumpers, targets, and flags. To change the keyboard controls, click the Options menu, and then click Player Controls. 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. 3D Pinball for Windows - Space Cadet is a pinball game included in Windows XP. 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. 3D Pinball for Windows - Space Cadet is a pinball video game included in Windows XP. A customer used their support contract to ask how to change among the three levels of play in Space Cadet Pinball.My proudest achievement of Windows XP was fixing the game so it didn’t consume 100 CPU.People keep asking if it can be brought back. I'm not aware of any good general-case automation for this. Space Cadet Pinball has a special place in the hearts of many Windows enthusiasts. ![]()
