Reason given: Figure out the status of each disassembly (non-matching, matching but incomplete, complete but poorly documented, well documented, etc., as well as whether the incomplete ones are being worked on or abandoned).


Many early Pokémon games have been disassembled, or otherwise reverse engineered to some extent. This page is a list of:

  • Disassembly projects of Pokémon games, attempts to reverse engineer Pokémon games into the assembly language (or a higher-level language). They are useful for glitch researching, as well as for creating ROM hacks. A good disassembly project should be:
    • Matching: The project could be built to faithfully reproduce the original ROM. A disassembly may be non-matching because of a problem with the automatic disassembling process that needs to be fixed manually, or because it is based on another disassembly of a similar game (e.g. the disassembly of Pokémon Red and Green is based on that of English Pokémon Red and Blue) and has not yet incorporated all the differences between those two games (e.g. the Japanese texts). For glitch researching, a matching disassembly is very useful, because the behaviors of glitches are often affected by minute details in the ROM.
    • Complete: The entire game should be disassembled. Incomplete disassembly projects can still be matching, but they will require a base ROM in order to build, because at some places the built ROM will include parts of the base ROM (e.g. with the INCBIN directive[1] of RGBDS).
    • Well documented: The disassembly should contain some extra information that makes the code easily human-readable. Common forms of such information include human-readable names for functions, variables and other labels; comments in the assembly code; human-readable data formats with constants and macros; and a good file structure to reflect modules in the game engine.
  • Memory maps, mappings between memory addresses and their in-game meanings. This includes RAM addresses (which usually correspond to variables that can be modified by the game) as well as ROM addresses (which usually correspond to static data, or pieces of the game's code). Even though this information could be derived from a good disassembly (e.g. they usually have files named "wram.asm", "sram.asm", etc. that define the RAM layout, from which the address of each variable could be determined by counting bytes), a memory map will make this process considerably easier. Also, building the disassembly will usually give a symbol file, which shows the correspondence between memory addresses and symbols (i.e. their names in the disassembly), and can also be used as a memory map.
  • Notes, miscellaneous information that may be helpful for understanding the disassembly projects.
