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.

In particular, allow to optionally add the mapper and submapper ID that
was found, so it can be displayed to the user.

fuzz: change names to have dashes instead of underscore2026-09-15T16:02:43ZMiquel Sabaté Solàmssola@mssola.com2026-09-15T16:02:43Zurn:sha1:01bb4fee8c45caee757b3bdc5432fd88dbcdfca3
From the latest update of Rust's stable channel, this was raised as a
bad format for fuzz names.

readrom: print the usual PRG-RAM size if available2026-07-13T15:37:43ZMiquel Sabaté Solàmssola@mssola.com2026-07-13T15:37:43Zurn:sha1:ef226a7e10fe665f025a0c4eed6e7dc0c613da4e
If 'has_persistent_memory' has been set on the ROM header, then we must
print it even if bytes 8/10 was never set by the header. In fact, the
vast majority of ROM files don't have these bytes set but they report a
true value for 'has_persistent_memory'. Hence, assume the usual PRG-RAM
size in these cases, which is (I hope) the correct one in all cases.

And also adjust the code so the clippy from the 2024 edition is fine
with it.

Update the code style to the latest stable Rust2026-04-24T13:04:10ZMiquel Sabaté Solàmssola@mssola.com2026-04-24T13:04:10Zurn:sha1:11790d769b9dc651f3218bdfe40da59c7c9d400e
This mostly involves applying the collapsible_match rule[1] where
appropiate, and using sort_by_key() as pointed out by the latest stable
version of clippy.
