Since there is no source code, only binary burning files, I wonder if ordinary 51 emulators can implement single-step tracking execution?

Yes, if you want pure hardware simulation, you need an emulator. This emulator is not an ordinary download cable, it is quite expensive

You can find an old-fashioned 51 development board online. The development board is designed to be executed by calling BIN files. If it is a DOS version of the development board, you need to install a DOS emulator on the PC. The current 51 development board can also be used in theory, but you should note that many 51s are enhanced versions, and the instruction execution speed is different.

It is indeed quite troublesome. The solution I can think of now is to use a logic analyzer to capture the bus signal and analyze it slowly.

That may be even more troublesome. It is better to redesign it from the overall function.
