This is a disassembly of Chip's Challenge for Windows 95.
It builds the following executable:
- CHIPS.EXE
sha256: 8e26acd67cf120bd5b512de4b4e78b80aca1579413cd04f3b2b68909a375866c
The core game logic has been disassembled and extensively commented; see logic.asm and movement.asm.
Almost all of the game's memory has been mapped out; see data.asm and structs.asm.
If you are interested in the address of a particular variable, check out variables.asm.
Most of the rest of the code has been disassembled but may lack useful function/data labels and comments.

To build, you'll need the following programs installed:
- make
- nasm
- awk
- golang
You'll also need an existing copy of CHIPS.EXE with the sha256sum given above,
to fill in the incomplete portions of the disassembly.
Go is required for building the linker and (optionally) some other tools.
Some tools require python3, but they aren't used in the build.
-
Copy the game executable to
base.exein this directory -
Run
make -
(optional) Run
make checkto compare the output with the base image.
