Profiles, the wiki, comments, docstrings, command output and schema descriptions carried em-dashes, clause-joining semicolons, unicode arrows, box-drawing banners and check-mark glyphs. Each sentence was rewritten rather than having its character swapped. Hashes, paths, source_ref values and every cited file:line are unchanged, which a comparison of each parsed profile against the previous revision confirms. validate_pr comments now say PASS and FAIL in words, and source_ref values in a profile's structured blocks render as code. test_prose_style fails if any of these comes back, in tracked files or in the generated site.

notes: |
|
|
Opera is the libretro port of the 4DO/FreeDO 3DO Interactive Multiplayer emulator.
|
|
The system ROM (rom1) is chosen by the opera_bios core option. Its default is
|
|
Opera Boot, an open boot ROM (trapexit/opera-boot) compiled into the core as a
|
|
zlib stream and inflated at load, so the core starts with no file at all. The
|
|
option lists the built-in ROM first, then each BIOS file physically present in
|
|
the system directory. A file is read with read_file_from_system_directory()
|
|
and byteswapped on little-endian hosts.
|
|
|
|
opera-boot.bin is the same Opera Boot image read from the system directory
|
|
("Opera Boot (System)"), for a newer build than the one compiled in.
|
|
|
|
Kanji font ROMs (rom2) are optional and only needed for Japanese text rendering.
|
|
They are loaded via opera_lr_opts_set_font() and selected via opera_font core option.
|
|
|
|
All BIOS files are exactly 1 MB (1048576 bytes) except opera-boot.bin (128 KB),
|
|
3do_arcade_saot.bin (512 KB) and panafz1-kanji.bin (933636 bytes).
|
|
|
|
BIOS definitions: BIOSES[] at libopera/opera_bios.c:9-164, built-in inflate
|
|
opera_bios_load_builtin() at libopera/opera_bios.c:234-267.
|
|
BIOS selection and loading: opera_lr_opts.c:276-359 (get_bios, _load_bios_rom,
|
|
set_bios). Font loading: opera_lr_opts.c:361-415.
|
|
Core option: libretro_core_options.c:752-783 (set_bios_values) lists the
|
|
built-in ROM and the files present.
