Each libretro profile records version_basis and core_version is read there at its pin. snes9x states 1.63 in snes9x.h, nestopia 2.0.0, mgba 0.11.0, vice 3.10, atari800's libretro tree 7.0.0. Cores whose build takes its version from git carry the nearest tag in describe form (flycast v2.7-90-ge88b0ce, ppsspp, duckstation, gearcoleco), placeholders copied from .info files (Git, SVN) are replaced by the code's statement, and a code that states none is null with kind none.

# QUASI88 by Showzoh Fukunaga, libretro port by Celerizer.
|
|
# Includes pseudo-BIOS (pbios_n88, pbios_disk) by cisc compiled into the core.
|
|
# With pseudo-BIOS, some disk-based games boot but compatibility is limited.
|
|

|
|
# ROM search order (src/LIBRETRO/libretro.c:977-1024):
|
|
# 1. <download_dir>/<filename>
|
|
# 2. <system_dir>/quasi88/<filename>
|
|
# 3. <system_dir>/<filename>
|
|
# Each ROM entry has up to 4 alternate filenames tried in order.
|
|
#
|
|
# ROM loading (src/LIBRETRO/libretro.c:1083-1127):
|
|
# N88.ROM and DISK.ROM have pseudo-BIOS fallback if missing.
|
|
# All other ROMs are loaded silently if present, ignored if absent.
|
|
#
|
|
# The original QUASI88 (src/memory.c:80-95) uses uppercase-first filenames
|
|
# (N88.ROM, N88EXT0.ROM, etc.) while the libretro .info file uses
|
|
# lowercase with underscore variants (n88.rom, n88_0.rom, etc.).
|
|
# The core tries both naming conventions.
|
|
#
|
|
# FONT.ROM/FONT2.ROM/FONT3.ROM are not in the .info file.
|
|
# When missing, the core uses built-in fonts (font.h) or kanji ROM glyphs.
|
|
#
|
|
# Upstream supports 2HD disk ROM (8 KB) via src/memory.c:356-368.
|
|
# The libretro port reads only 2 KB (2D type) at src/LIBRETRO/libretro.c:1085.
|
|
#
|
|
# font.rom divergence: src/LIBRETRO/libretro.c:1099-1104 loads 0x1000 bytes then
|
|
# overwrites the buffer with kanji ROM + built-in graph. The font.rom
|
|
# data ends up unused. Upstream src/memory.c:427 loads FONT_SZ
|
|
# (2048) and keeps the font data in the first half.
|
|
#
|
|
# OPNA rhythm samples (2608_BD.WAV etc.): loaded by upstream via
|
|
# src/fmgen/opna.cpp:1271 LoadRhythmSample(), but osd_dir_rom() returns
|
|
# NULL in the libretro port (dir_rom never initialized), so the samples
|
|
# cannot be loaded. OPNA rhythm playback is silent in the libretro core.

|
|
The pseudo-BIOS covers N88-BASIC V2 and the disk subsystem at a basic
|
|
level. For full compatibility (N-BASIC, V1H/V1S modes, dictionary lookup,
|
|
kanji display), real ROM files are needed.
|
|
|
|
Core option "quasi88_basic_mode" selects N88 V2, N88 V1H, N88 V1S,
|
|
or N mode. Each mode requires its corresponding ROM. N mode emulates
|
|
PC-8001 series (N-BASIC) and requires n88n.rom.
