tl;dr: A hobbyist reverse-engineering the 1989 DOS game F-15 Strike Eagle II has finished reconstructing the C source code for all executables, far ahead of schedule. The project (v0.9.1) is now seeking testers to drop the rebuilt binaries into an original game install (version 451.03 with Desert Storm expansion) and report crashes, graphical glitches, or input issues. Since it's a bug-for-bug reconstruction, testers should verify reported issues aren't also present in the original game.
