I've analyzed quite a lot of emulators source code, including qemu as well.
But I somehow would like to completely get rid of emulators, and simply
convert
application from one cpu/board to another cpu/board.

In general, this is not possible. Consider for example self-modifying
or otherwise dynamically created code, or just code that examines
itself.
In some specific trivial cases it could work, and QEMU could be made
to abort if translation would be needed.

Hi !
I think self-modifying code is kinda rare case - it's made typically for
protection againt hackers , and typically on pc side. Nintendo roms probably
don't use this kind of
protection.
It doesn't have to be protection, for example GCC generates
trampolines to stack when using

On wiki pages this is called binary translation.
