Thusly, it's known that DAA instruction doesn't yield correct result after subtration but it's not known why and AC flag has mysterious ways too.. Just recently a few enthusiastic people from a Russian Vector-06c fans forum found a piece of software for Vector-06c which could not be started in any of the existing emulators, couldn't be started in my FPGA replica yet had no problem running in the real Vector-06c at all. After some investigation it turned out that 8080 ALU had AC flag inverted after SUB operation. This involves SUB, SBB, SBI, DCR, CMP, CPI instructions.
