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.

Upgrade to the 2024 edition of Rust2026-07-08T19:09:42ZMiquel Sabaté Solàmssola@mssola.com2026-07-08T18:45:05Zurn:sha1:6333dc7ee02332cd06e20b56cefd3210368e54f8
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.

Add the readrom binary2024-12-18T06:46:26ZMiquel Sabaté Solàmikisabate@gmail.com2024-12-18T06:46:26Zurn:sha1:407048d0037c8d6d26c7e3fe2384e974212f124e
The readrom binary is similar to `readelf` from Linux and it will allow
to display information from an NES/Famicom ROM file. For now the
information being shown is just the header, but in the future we might
also include disassembling parts of the code, or retrieving the "CHARS"
section for a given ROM file, and similar.
In order to implement the header parsing part a new library has been
introduced, simply named "header" which abstracts everything away so you
just need to call `Header::try_from("my bytes")` to fetch the actual
information.
