By file access I meant "load the contents of this file to the simulated
memory here" and "save the contents of simulated memory here, size N, to
this file". Which is comparable to other hw simulators of similar
ability. I'm sure it can be hacked by directly editing the python when
running, but explicit support is user-friendly.
Such an isolated simulator is on the edge of whether it makes sense to
act now or not. Having to isolate each func, and extract various test
data gets old fast (vs running a full binary against full files).
Running a full ffmpeg binary is certainly not possible under it. I will
think about it.
