Accuracy of Saturn CPU emulators

[ldesnogu]

Hello,

I am wondering what the most accurate Saturn CPU emulator is (I am talking of the CPU emulator accuracy rather than the full calculator one).

Reading Hrast page about his emulators on HP 49g+/HP 50, it looks like the Saturn emulator used by those calculators was not fully accurate, in particular for BCD computation.

Is Christoph Gießelink and Sébastien Carlier Emu48 the most accurate one? I think I read somewhere that Christoph ran many tests on his calc to ensure accuracy (but can't find the info any more). I wonder how far this was pushed.
