Hmmm it might have then compiled to something resembling the original machine code.

“Emulator” is an awkward word, but it’s the best I can come up with at this time in the morning.

The “emulation” is at the source level, if you will. The “emulator” is mainly C data and preprocessor macros, and the original assembly has been modified into macro invocations which expand into C source for the compiler.

Its a transcoder, or a source converter.

Bingo! (ETA: Although there IS an emulated 6502 core, registers and all, within the compiled program). Thanks.

It’s not that much. I still write 8 bit PIC assembly language code for parts of the telescope I work on, and of course my Nixie watches. Several of these programs are over 2k.

I asked my brother about his 6800 chess program - he converted it to two pages of Python about 15 years back.
