# OpenMM2: a bottom-up Midtown Madness 2 rewrite

> OpenMM2 rewrites Midtown Madness 2 from the bottom up in C++, using the installed game's original binary to supply functions that have not yet been reimplemented. The project aims to make game fixes, new features and ports possible, but its author describes it as mostly abandoned because of technical limits.
