Could you build this?
No Binary patching a 1990s MS-DOS x86 executable (Ultima Underworld) to modify software rendering routines for perspective correction requires deep reverse engineering, x86 assembly, and retro software rasterization knowledge.
What it would actually take: Requires disassembling the real-mode/protected-mode x86 DOS binary (UW.EXE) using IDA Pro or Ghidra, reverse-engineering the fixed-point 2.5D floor/ceiling texture-mapping rasterizer, writing replacement x86 assembly routines that compute perspective-correct interpolation per-span, and creating a byte patcher that redirects execution without breaking game memory or state. This requires specialized expertise in vintage software reverse engineering and legacy 3D graphics algorithms.
