The current project is almost entirely C code. The only .S files are
crt0.S and some data tables.

Inline assembly is used where speed matters. On the NES that is
mostly when writing to the video tile buffer, which can corrupt the
display if done outside of the video blanking interval. For just
about everything else, C code with -Oi is fast enough.
