Python library for Acorn ROM Filing System (ROMFS) paged-ROM images

Project description

oaknut-romfs

Acorn ROM Filing System (ROMFS) support for the oaknut family of packages.

ROMFS is the filing system for paged ROMs on the BBC Micro and Acorn Electron — sideways ROMs and cartridges. It stores files in the same block layout as the Cassette Filing System (CFS), with the ROM image standing in for the tape: each file is a chain of CFS-format blocks carrying Acorn load and execution addresses, a block number, a length, a flag byte, and header and data CRCs, introduced by a standard paged-ROM service header.

The medium is read-only ROM, so the filing system is flat: there are no directories, and a file's metadata is the load/exec pair plus a lock bit, exactly as on cassette.

This package contributes ROMFS to the oaknut.filesystem extension axis, so ROMFS images are identified, listed and read through the disc CLI alongside the disc-based filing systems.

Status

Pre-alpha. The package is being built up format-first: see docs/romfs-format-spec.md for the on-ROM byte layout and docs/architecture.md for the package design and its mapping onto the oaknut.filesystem contract.
