readrom: add support for default expansion device2026-10-06T15:27:50ZMiquel Sabaté Solàmssola@mssola.com2026-10-06T15:15:16Zurn:sha1:4bf12db91feb5db98d65b518dbad0c1a8c6748df
The 15th byte from the NES 2.0 header was wilfully ignored, but it can
be relevant to the end user. Hence, add support for it in the 'header'
library, and add the frontend code into 'readrom'.
The point is not to support every single thing out there, but I have
added the stuff that I thought was most relevant, and we can add more
items to it whenever the need appears.

readrom: add support for MMC32026-10-06T15:06:39ZMiquel Sabaté Solàmssola@mssola.com2026-10-06T15:06:39Zurn:sha1:b2ec385bf83ad895208e7eb481f704cf8a12a6c6
In theory it's support for any kind of memory mapper, but in practice
only MMC3 has been added.

Annotate the no-return from die()2026-08-24T12:16:42ZMiquel Sabaté Solàmssola@mssola.com2026-08-24T12:16:42Zurn:sha1:ef5cacef65bed736ee0bdff7426684b3c1b5e35f
In all crates we are using a die() function to print to stderr and quit
with a exit status > 0. Apparently in Rust you can annotate the return
type with a bang just like the noreturn from the C family.
The added bonus is that some useless statements to make the compiler
happy without it can be removed altogether as now the compiler is able
to understand that it won't return so the returned type is not needed.

readrom: read the ROM file right on start2026-07-23T10:45:59ZMiquel Sabaté Solàmssola@mssola.com2026-07-19T20:50:07Zurn:sha1:f367d25f0d9d7f0e7580a47294f792143fbb6784
This avoids exhausting the input in other scenarios (thus fixing commit
f5549b97bf85 ("readrom: only read the ROM file once")), and it makes
everything more cohesive.
