RealDOOM: Running DOOM on 16-bit Processors

RealDOOM is a work-in-progress port of the DOS version of DOOM (based on PCDOOMv2) to real mode, aiming for accuracy to the original game. Currently supporting DOOM1 and DOOM2 WADs, with plans for Ultimate DOOM. Development focuses on ASM rewrites of the render code and restoring removed features like sound and save games. While there are limitations on texture size and node counts, the project boasts performance benchmarks across various processors and quality settings.
