This page aspires to list, identify and supply all ROMs available for the BBC Micro and related computers. A green tick ✓ marks a 'known good' ROM image. Additions and corrections are welcomed.

Searching: type words, "phrases in quotes", -exclusions (e.g. -hacked), or a checksum. Each ROM's *HELP text is searched too, so e.g. format also finds the ROMs with a FORMAT command. Press / to jump to the search box. To identify a ROM image file, drop it anywhere on the page, or use Identify a ROM…. This also recognises a file made up of ROM images from the library, e.g. two 8K ROMs in one 16K file.

Brief explainer: The BBC Micro has four sockets for 'sideways ROMs'. Expansion boards increase this number. One contains BBC BASIC by default, and another often holds a filing system such as ADFS.

ROM images are usually 16K as this is the size the BBC Micro understands. Smaller ROM images are routinely padded or duplicated to make the total length 16K. Larger products can be supplied on multiple 16K ROMs. A single ROM image larger than 16K needs additional hardware e.g. the Integraβ expansion board. The Operating System ROM has a separate dedicated socket, and is not a sideways ROM.
