# Primal Rage: DOS engine reconstruction and SDL3 port

> Primal Rage RE reconstructs the DOS game's engine in C over a memory layout matching PRAGE.EXE and runs it with SDL3 using the user's game data. The project includes Ghidra analysis scripts, LE and resource-format documentation, captures and differential checks; the author reports all 759 game-owned functions ported.
