Decompilation
The technique of reverse-translating compiled machine code or bytecode into a high-level language form close to the original source code, making the code readable and modifiable. It is widely used in game ports and reverse engineering.
Core Facts
Decompilation is the process of restoring machine code or bytecode to a human-readable high-level language, whereas disassembly only restores code to the assembly level
A decompiler converts machine code into assembly and then further restores it into C-like pseudocode, whereas a disassembler only translates machine code into assembly instructions.

Decompilation is abstracting assembly into C-like pseudocode, recovering loop, conditional, and function call structures, but it loses some information and naming relies on guessing.
A decompiler converts machine code into assembly and then further restores it into C-like pseudocode, whereas a disassembler only translates machine code into assembly instructions.
Emulators run old game machine code on modern devices by simulating the original hardware environment in software, whereas decompilation reverses compiled binary machine code back into human-readable high-level language code (typically C or C++).
Compilation is a lossy process—semantic information such as variable names, comments, type information, and high-level control flow is discarded at compile time—so decompilation is fundamentally an information reconstruction problem with no single correct answer.
The correctness of decompilation results requires compilable, executable feedback signals to drive agent iteration.
Traditional game decompilation relies heavily on manual reverse engineering, using professional disassembly tools such as IDA Pro and Ghidra to translate machine code into assembly instructions.
Decompilation is the process of reverse-engineering source code from a known output (machine code execution results) through a guess-and-verify loop.
Decompilation results are not the original source code; variable names are typically obfuscated or represented by placeholders such as var_1 and sub_4012A0
