Note that the "blinking" problem is still there, but the 1st step before we can fix that is ensure that the transition from ios 4 and android 11 or so went smoothly!

Are these apps based on running the original Nut firmware in an emulator, or are they based on functional reimplementations? In the first case, here are a few collected threads discussing some of the open issues (just in case you missed one of them, though unlikely):

HP-15C:

CHS stack lift bug (and fix):

There were also patches to support more memory (up to ca. 230 registers or ca. 1600 program steps) which could be incorporated into an emulator as well. Ideally this would be made configurable in a user setting for maximum backward compatibility.

https://www.swissmicros.com/firmware/history.txt (mentions two bug fixes for extended memory patches - not sure if they applied to the Nut firmware image or the emulator)

HP-15c Limited Edition:
