* readrom: Remove the derive feature from clapMiquel Sabaté Solà2025-01-102-14/+18
| | | | | | | This allows us to statically build the 'readrom' binary, as that feature from clap prevented that option. Signed-off-by: Miquel Sabaté Solà <mikisabate@gmail.com>
* Remove anyhow from xa65 and readromMiquel Sabaté Solà2025-01-102-9/+17
| | | | | | | | Following in the footsteps of c20c991dded8 ("Make errors from nasm itself more cohesive"), 'anyhow' might provide an easy framework, but it lends towards a less cohesive experience. Signed-off-by: Miquel Sabaté Solà <mikisabate@gmail.com>
* Add the readrom binaryMiquel Sabaté Solà2024-12-182-0/+67
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.
