feat: re-profile 22 emulators, refactor validation to common.py
batch re-profiled nekop2 through pokemini. mupen64plus renamed to mupen64plus_next. new profiles: nes, mupen64plus_next. validation functions (_build_validation_index, check_file_validation) consolidated in common.py — single source of truth for verify.py and generate_pack.py. pipeline 100% consistent on all 6 platforms.

notes: |
|
||||
Libretro port of PCSX2. Uses the same BIOS files as standalone PCSX2.
|
||||
BIOS must NOT be zipped. Any valid PS2 BIOS works (SCPH-10000 not
|
||||
recommended due to lower compatibility). BIOS goes in pcsx2/bios/.
|
||||
GameIndex.yaml goes in pcsx2/resources/ and is needed for proper
|
||||
game-specific settings (patches, fixes).
|
||||
Hard fork of PCSX2 ported to libretro. BIOS detection is filename-agnostic: the core
|
||||
scans pcsx2/bios/ for any file between 4-8 MB with a valid romdir structure containing
|
||||
RESET and ROMVER entries. The ROMVER entry determines region and version.
|
||||
Companion files (.rom1, .rom2, .nvm, .mec) derive their paths from the selected BIOS.
|
||||
DEV9 (network adapter) and USB are stubbed in the libretro port.
|
||||
GameIndex.yaml in pcsx2/resources/ provides per-game patches for compatibility.

NstDatabase.xml is an optional game database used for region autodetection,
|
||||
aspect ratio selection, and 4-player adapter recognition. A copy is baked
|
||||
into the core binary (libretro/nstdatabase.hpp) and used as fallback when
|
||||
no external file is found. Placing a newer NstDatabase.xml in the system
|
||||
directory overrides the built-in copy.
|
||||
NstDatabase.xml is an optional game database for region autodetection,
|
||||
mapper selection, and 4-player adapter recognition. A copy is baked into
|
||||
the core binary (libretro/nstdatabase.hpp) as fallback. The upstream
|
||||
Nestopia JG requires this file; the libretro port makes it optional.
|
||||
|
||||
An optional custom palette file (custom.pal, 192 bytes, 64 RGB triplets)
|
||||
overrides the built-in palettes when the nestopia_palette core option is
|
||||
set to Custom. The core ships with 10+ built-in palettes (Royaltea,
|
||||
Smooth FBx, etc.) so the external file is rarely needed.
|
||||
An optional custom palette file (custom.pal, 64 RGB triplets) overrides
|
||||
built-in palettes when the nestopia_palette core option is set to Custom.
|
||||
The libretro port embeds all named palettes (Royaltea, Smooth FBx, etc.)
|
||||
that the upstream loads from external .pal files.
|
||||
|
||||
Audio samples for specific games can be placed in system/nestopia/samples/
|
||||
as numbered .wav files (e.g., 00.wav, 01.wav). This is used for Famicom
|
||||
expansion audio in a few titles.
|
||||
|
||||
Game Genie is handled as cheat code decoding (software), not via a ROM file.
|
||||
|
||||
File path construction: libretro/libretro.cpp retro_load_game() joins the
|
||||
system directory (RETRO_ENVIRONMENT_GET_SYSTEM_DIRECTORY) with each
|
||||
filename directly - no subdirectories.
|
||||
Five Famicom games use external ADPCM audio samples placed in
|
||||
system/nestopia/samples/{game}/ as numbered .wav files. These originate
|
||||
from MAME sample ZIPs. Games function without them but miss some audio.

Libretro port of Wabbitemu, a TI-83 family calculator emulator.

in the system directory root with a fixed priority order

(libretronew.cpp:575-594):
|
||||
A calculator ROM dump is required. The core searches sequentially in the
|
||||
system directory (libretronew.cpp:575-594): ti83se.rom first, then
|
||||
ti83plus.rom, then ti83.rom. The first found is loaded via rom_load()
|
||||
(libretronew.cpp:608). file_present_in_system() checks existence only
|
||||
via VFS open/close (libretronew.cpp:451-472). No hash or size validation.
|

|

1. ti83se.rom (TI-83 Silver Edition, recommended -- largest storage)
|
||||
2. ti83plus.rom (TI-83 Plus)
|
||||
3. ti83.rom (TI-83)
|
||||
Without any ROM, the core shows a blank screen listing the expected
|
||||
filenames (libretronew.cpp:1030-1042). No HLE fallback.
|
||||
|
||||
The first file found wins. file_present_in_system() checks existence only
|
||||
(libretronew.cpp:451-472), then rom_load() loads it (libretronew.cpp:608).
|
||||
Supports no-content launch (libretronew.cpp:556). Content files
|
||||
(.8xp/.8xk/.8xg) are loaded on top of the running ROM via link cable
|
||||
simulation. Auto-saves calculator state every 10 seconds
|
||||
(libretronew.cpp:1050-1063).
|
||||
|
||||
There is no fallback or built-in ROM. If none of the three files are found,
|
||||
the core starts without a BIOS and shows a blank screen with a status
|
||||
message listing the expected filenames (libretronew.cpp:1034-1041).
|
||||
|
||||
The core supports no-content launch (RETRO_ENVIRONMENT_SET_SUPPORT_NO_GAME
|
||||
is set to true, libretronew.cpp:555-556). Content files are .8xp/.8xk/.8xg
|
||||
calculator programs loaded on top of the running ROM.
|

|
||||
The emulator auto-saves calculator state every 10 seconds to preserve RAM
|

contents (the TI-83 has no persistent storage beyond battery-backed RAM).
|

Upstream Wabbitemu supports a wider model range (TI-73 through TI-84+CSE)
|

but the libretro wrapper only searches for TI-83 family filenames. The

The core requires the original freeware Cave Story distribution placed in
|
||||
{system_dir}/nxengine/. When launched without a content file, it looks for
|
||||
Doukutsu.exe at that path (libretro.cpp:254-259). When launched with a .exe

|
||||
content file, it uses the parent directory of that file (libretro.cpp:237).
|
||||
|
||||
At startup (main.cpp:66-90), the core opens Doukutsu.exe and extracts from
|
||||
it: ORG music files (extractorg.c), PXT sound effects (extractpxt.c), stage
|
||||
tile attributes (extractstages.c), bitmap graphics, and the wavetable
|
||||
(cachefiles.c:484). These are kept in memory, not written to disk.
|
||||
At startup (main.cpp:75-90), the core opens Doukutsu.exe and extracts:
|
||||
ORG music (extractorg.c), PXT sound effects (extractpxt.c), stage tile
|
||||
attributes (extractstages.c), 18 credit BMPs + pixel.bmp (endpic/),
|
||||
and the wavetable (cachefiles.c:464-485). All kept in memory.
|
||||
|
||||
The data/ directory must exist alongside Doukutsu.exe with the full game
|
||||
asset tree: 30 root-level files (sprites, backgrounds, script tables),
|
||||
36 NPC sprite sheets in data/Npc/, and 333 stage files in data/Stage/
|
||||
(maps .pxm, tile attributes .pxa, entity lists .pxe, scripts .tsc, and
|
||||
tileset images via Prt*.pbm). The core verifies data/ exists by checking
|
||||
for data/npc.tbl (main.cpp:47-63).
|
||||
The data/ directory (399 files from the freeware release) is loaded into
|
||||
an in-memory cache at init (cachefiles.c:38-439, 497-540). All subsequent
|
||||
file access goes through this cache. The core verifies data/ by checking
|
||||
for data/npc.tbl (main.cpp:47-58).
|
||||
|
||||
The core also reads endpic/ bitmaps for ending sequences, extracted from
|
||||
Doukutsu.exe at runtime (cachefiles.c:460-484).
|
||||
The font is compiled-in (bitmap_font.h). The upstream standalone version
|
||||
uses font.ttf via SDL_ttf.
|
||||
|
||||
All required files ship in the datafiles/ directory of the libretro repo
|
||||
itself, since Cave Story is freeware. No separate BIOS or firmware is
|
||||
needed. The entire freeware distribution is the "system" requirement.
|
||||
|
||||
sprites.sif has a compiled-in fallback (sprites_sif.h) and is the only

data file that can be missing without a fatal error (cachefiles.c:515-521).

|

notes:
|

rom_structure: >
|
||||
All ROM files are loaded relative to the RetroArch system directory via
|
||||
romfopen(). Machine BIOS ROMs go in roms/<machine_name>/ subdirectories.
|
||||
Video card ROMs go directly in roms/ (or roms/<card>/ for some).
|
||||
Which ROMs are needed depends on the selected machine model and video card.
|
||||
minimum_requirement: >
|
||||
At minimum, mda.rom (font) and one machine BIOS set are required.
|
||||
The video card ROM for the selected GPU is also needed unless the machine
|
||||
has built-in video (PCjr, Tandy, Amstrad, Acer 386SX, PS/1).
|
||||
libretro_version: >
|
||||
The libretro port is PCem-mooch v11, a community fork based on PCem v10.1.
|
||||
Upstream PCem has evolved to v17 with many more machines and devices.
|
||||
nvr_files: >
|
||||
NVR files are CMOS/NVRAM templates providing pre-configured BIOS settings.
|
||||
Shipped with the PCem distribution. Without them the BIOS starts with blank
|
||||
CMOS (user must manually configure). The emulator also writes these back on
|
||||
shutdown.
|
||||
runtime_state: >
|
||||
The emulator creates additional state files during operation: ATI EEPROM
|
||||
(ati18800.nvr, ati28800.nvr, mach64.nvr), Intel flash (dmi.bin, escd.bin
|
||||
per Pentium machine). These are emulator-generated and not included here.
|
||||
info_divergence: >
|
||||
The .info declares zero firmware (no firmware_count field). The core
|
||||
actually loads 89+ ROM files plus NVR/EEPROM templates.

Mega CD / Sega CD games require a region-matching BIOS file. The core searches

the system directory for each name in order, trying .bin then .zip extension,

and uses the first file found. If no BIOS is found, CD games fail to load with

The libretro frontend does not expose any 32X BIOS loading path. Only the
