<p>Got as far as the raw binary for a 16 bit DOS executable. Running it produces no output, the ASM seems to null registers using an XOR and then do some comparisons against various states. There&#39;s also some iteration against the stack pointer, which seems to move the stack frame by 65036 every iteration. Strange, but I&#39;m getting somewhere. </p>
