spgame

Repo for documenting client functions in a defunct MORPG "Survival Project".

Introduction

This repo is created by HKG 巫毒兔子, an hobbyist enthusiast in reverse engineering. This repo is maintained by our contributors' support. The project attempts to construct an SPGAME server by reversing the mechanisms in the game client... from scratch!

This repo contains the products and work-in-process for recovered functions in the game client:
./asm for raw assembly
./src for recovered C++-style functions
./comments general comments about functions/data ``` fork me ``` Intel Pentium Instruction Set Reference
x86 Instruction Reference
