![]() 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. Obviously, difficulty is subjective but when pinball is known for its quick, pick up and play nature, it’s a little off putting that you’ll have to set aside hours of your day just to play a few games.I'm not aware of any good general-case automation for this. You’ll find that you’ll have to play for up to an hour just to get anywhere near your best score. 3D Ultra Pinball Thrillride simply can’t compete in terms of visual refinement and the physics within this title, while completely serviceable, are far from the total realism that its competition provides.Īlso, while the gameplay is varied, sectioned off and unique, its also very easy. ![]() It has to be said that the game doesn’t compare to the Pro Pinball series, its closest rival. While the gameplay is fun and the thematic direction is great. It’s a unique approach to creating a Pinball experience and one that keeps things fresh, even in those long sessions where you’re on the hunt for a new high score. You’ll have to get your ball into specific sections of the table and complete a series of tasks to progress. Then speaking of the gameplay, this pinball outing really focuses on delivering an overall experience to the player beyond hitting a ball aimlessly. It’s a fun theme that does all it can to offer the magic of pinball without straying outside the realms of reality, allowing the gameplay to still retain its realism. ![]() This game takes on a carnival style amusements sort of theme, complete with wacky designs and table-based sounds and animations that offer whimsy when playing. First and foremost, let’s talk about the theme of this title, as this is where a lot of the differences from other 3D Ultra Pinball games will lie. ![]()
