Extended emulator of МК 61/54 app

Extended emulator of МК 61/54 is Science & Education application that is open source under the GPL-3.0-only license. МК 61 was the best seller of all USSR programmable calculators of 1980-s (B3-34, MK-54, MK-56, MK-61, MK-52).

Calculators are emulated on microcode level so they behave exactly like the original devices, including all non-documented features and inaccurate calculations. For ease of use application features saving and loading emulation states.

This app's emulation engine Java code is based on C++ source of Felix Lazarev's emu145 project.
Emulation was highly optimized for speed and should run in real time on any phone.

It's an extended version of the original emulator МК 61/54 by Stanislav Borutsky
