Spice86 – A PC emulator for real mode reverse engineering
Reverse engineer and rewrite real mode DOS programs! - GitHub - OpenRakis/Spice86: Reverse engineer and rewrite real mode DOS programs!
Spice86 is a tool to execute, reverse engineer and rewrite real mode DOS programs for which source code is not available.
