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. They may differ from the exe you are running because DOS programs can rewrite some of their instructions / load additional modules in memory. This is the behaviour that is activated with parameter--InstructionsPerSecond and is forced when in GDB mode so that you can debug with peace of mind without the timer triggering.
