Case study

Gunboat: a function-level C++ port of the DOS game

Gunboat reconstructs the 1990 DOS game Gunboat: River Combat Simulation in C++ and SDL3, porting functions from GB.EXE and reading the player's original data at runtime. It includes an executable map, subsystem specifications and differential tests against original code; the author reports native gameplay across the original video modes.
