feat: re-profile 30 emulators, beetle to parallel_n64

source-verified: mesen FdsBios.bin→alias, MesenDB.txt phantom (embedded). mupen64plus 64DD_IPL.bin→IPL.n64 (code path fix). neocd 000-lo.lo/ng-lo.rom phantoms (algorithmically generated). new profiles: mesen-s, mupen64plus next develop/gles2/gles3. regenerate database.

 notes: |
-  Beetle Saturn is the libretro port of Mednafen's Sega Saturn emulation module.
-  Two region-specific BIOS files are used: sega_101.bin for Japan/Asia NTSC,
-  mpr-17933.bin for North America, Europe, and all other regions. The core
-  returns false from InitCommon() if the BIOS file is missing or not exactly
-  512 KB, so both BIOS files are required for full region coverage.
+  Libretro port of Mednafen's Saturn emulation module, frozen circa v0.9.45.1
+  (2017) with some later backports. Region auto-detection reads the disc header
+  and selects the matching BIOS. Manual override via beetle_saturn_region option.

-  Region auto-detection reads the disc header and picks the matching BIOS.
-  Manual region override is available via beetle_saturn_region core option.
+  InitCommon() returns false if the BIOS file is missing or not exactly 512 KB.
+  Both region BIOS files are required for full region coverage.

-  The KOF95 and Ultraman ROM carts are optional game-specific expansion
-  cartridges loaded from the system directory. The Action Replay 4M Plus
-  cart (satar4mp.bin) is listed but marked unfinished in source (needs
-  CPU UBC emulation).
+  KOF95 and Ultraman ROM carts are loaded when the cart type is set via core
+  option or auto-detected from the internal game database.

-  BIOS loading: mednafen/ss/ss.cpp InitCommon() lines 920-961.
-  Cart loading: mednafen/ss/cart.cpp CART_Init() lines 128-220.
-  Firmware path: libretro.cpp MDFN_MakeFName(MDFNMKF_FIRMWARE) -> system dir.
-  Default cart ROM filenames: mednafen/settings.cpp MDFN_GetSettingS().
+  Upstream Mednafen (1.32.x) has ST-V arcade board support (3 additional BIOS
+  files) and bootable ROM cart support, both absent from this libretro port.

+  Fork of Mednafen's pce_fast module with SuperGrafx and CD support.
+  Separate codebase from beetle_pce (mednafen/pce_fast/ vs mednafen/pce/).
+  BIOS loaded via HuC_LoadCD() at CD-ROM load time. Core option "sgx_cdbios"
+  selects which card image to use (default: System Card 3).
+  DetectGECD() auto-detects Games Express discs and overrides to gexpress.pce.
+  DetectSGXCD() detects SuperGrafx CD titles via magic bytes.
+  Arcade Card mode (sgx_arcadecard option, not exposed) extends System Card 3
+  with extra RAM mapping.
+  No hash or size validation on BIOS load.
+  Upstream pce_fast module has a single pce_fast.cdbios string setting;
+  the 4-option dropdown is a libretro addition. Upstream has no separate
+  gecdbios setting (unlike the accurate pce module).

 notes: |
-  MelonDS includes a built-in FreeBIOS replacement for basic DS mode (NTR).
-  Native BIOS/firmware files are required for DSi mode and recommended for
-  full DS compatibility (Key1 crypto for cartridge auth).
-  ARM9 BIOS size: 0x1000 (4 KB), ARM7 BIOS size: 0x4000 (16 KB).
-  DSi BIOS size: 0x10000 (64 KB) each.
-  Config keys: DS.BIOS9Path, DS.BIOS7Path, DS.FirmwarePath,
-  DSi.BIOS9Path, DSi.BIOS7Path, DSi.FirmwarePath, DSi.NANDPath.
+  FreeBIOS fallback for DS mode (NTR); DSi mode requires all native files.
+  Libretro fork based on melonDS ~0.9.x era, validates size only.
+  Upstream adds CRC32 validation on BIOS files (MemConstants.h).
+  DSi SD card emulation controlled by melonds_dsi_sdcard core option.

-  The libretro port does NOT load or use any external BIOS file. The core has
-  a complete HLE BIOS implementation (ameteor/source/bios.cpp) that handles
-  GBA SWI calls directly in C++. When no real BIOS is loaded (HasBios() returns
-  false), Cpu::SoftwareInterrupt() dispatches SWI calls to the HLE handlers
-  instead of executing the BIOS ROM (ameteor/source/cpu.cpp:244-311).
-
-  The standalone frontends (GTK, text) expose LoadBios() for optional real BIOS
-  loading, but the libretro port (libretro/libretro.cpp) never calls LoadBios()
-  and never queries RETRO_ENVIRONMENT_GET_SYSTEM_DIRECTORY. The retro_load_game()

-  (0x0E for 8-bit, 0xF00E for 16-bit, 0xE1B0F00E for 32-bit) when no BIOS is

-# mkxp-z is an open-source player for RPG Maker XP, VX and VX Ace games.
-# Heavily modified fork of mkxp implementing the RGSS (Ruby Game Scripting
-# System) interface versions 1, 2 and 3.
-#
-# The libretro .info file (mkxp-z_libretro.info) declares 3 firmware entries,
-# all optional. These are RTP (Run-Time Package) directories, not individual
-# files. Each RTP contains default assets (tilesets, sprites, music, sound
-# effects, fonts) shared by games that don't bundle their own.
-#
-# Games that ship all assets internally need no RTP at all.
-#
-# firmware0: mkxp-z/RTP/Standard   (RPG Maker XP RTP)   optional
-# firmware1: mkxp-z/RTP/RPGVX      (RPG Maker VX RTP)   optional
-# firmware2: mkxp-z/RTP/RPGVXAce   (RPG Maker VX Ace RTP) optional

-# RTP installers are available from https://www.rpgmakerweb.com/run-time-package
-# On non-Windows, use innoextract to unpack the Windows installers.
-#
-# RTP path resolution (sharedstate.cpp:144-145, config.cpp:326):
-#   config.rtps[] is populated from the "RTP" JSON array in mkxp.json.
-#   The libretro port sets these to <system_dir>/mkxp-z/RTP/<name>.
-#   Each path is added to PhysFS search path via fileSystem.addPath().
-#
-# Additional optional directories:
-#   mkxp-z/Fonts/                  custom fallback fonts (.otf/.ttf)
-#   mkxp-z/Scripts/Preload/        Ruby scripts run before game scripts
-#   mkxp-z/Scripts/Postload/       Ruby scripts run before rgss_main (RGSS3)
-#
-# MIDI playback: mkxp-z uses FluidSynth internally. A soundfont can be
-# specified per-game in mkxp.json via "midiSoundFont". No global soundfont
-# file is declared as firmware.
-#
-# Supported extensions: ini, json, rxproj, rvproj, rvproj2, mkxp, mkxpz, zip, 7z
-# Required GPU: OpenGL Core >= 2.0 or OpenGL ES >= 2.0

-  No individual BIOS or firmware files required. The three RTP directories
-  listed below are optional collections of default game assets. Only needed
-  when a game references stock RPG Maker assets instead of bundling them.
+  Game engine implementing RGSS 1/2/3 (Ruby Game Scripting System) for
+  RPG Maker XP, VX and VX Ace. Fork of Ancurio/mkxp. Libretro port by
+  white-axe, not yet merged upstream.

-  RPG Maker XP uses RGSS1 (Ruby Game Scripting System 1).
-  RPG Maker VX uses RGSS2.
-  RPG Maker VX Ace uses RGSS3.
-
-  Each RTP is a directory tree containing Audio/ and Graphics/ subdirs,
-  plus Fonts/ for VX and VX Ace. These are not hashable single files.
+  All entries are directories, not individual files. No hashable BIOS.
+  RTPs are shared asset packages needed only when a game references stock
+  assets instead of bundling its own. MIDI soundfont (GMGSx.sf2) is
+  embedded in the binary.

 notes: |
-  NeoCD is a dedicated SNK Neo Geo CD emulator. It supports Front Loader,
-  Top Loader, and CDZ hardware variants. BIOS files go in {system_dir}/neocd/
-  subdirectory (src/path.cpp:7, src/libretro_bios.cpp:76-81).
+  Complete rewrite of NeoCD in C++11. Scans {system_dir}/neocd/ for any .rom
+  or .bin file, also inside .zip archives (src/libretro_bios.cpp:69-105,
+  src/path.cpp:6 NEOCD_SYSTEM_SUBDIR = "neocd").

-  The core scans the neocd/ directory for any .rom or .bin file (also inside
-  .zip archives), reads the first 512 bytes, and identifies the BIOS type by
-  binary pattern matching at fixed ROM addresses (src/bios.cpp:168-208).
-  Filenames listed in the .info are conventional but not enforced by the core.
+  BIOS identified by binary pattern matching at fixed ROM addresses, not by
+  filename (src/bios.cpp:167-206). Files are auto byte-swapped if needed
+  (src/bios.cpp:148-160). Files smaller than 524288 bytes are skipped
+  (src/libretro_bios.cpp:42).

-  Three hardware families are detected: Front Loader (NeoCD), Top Loader
-  (NeoCD), and CDZ. Modified BIOS variants are also recognized: SMKDan 0.07,
-  SMKDan 0.07b, Universe BIOS 3.2, and Universe BIOS 3.3. The core applies
-  speed hack patches and CD recognition patches at load time for each type
-  (src/bios.cpp:209-280).
+  Three hardware families detected: Front Loader, Top Loader, CDZ. Modified
+  variants recognized: SMKDan 0.07, SMKDan 0.07b, Universe BIOS 3.2,
+  Universe BIOS 3.3 (src/bios.h:11-27). Any single valid BIOS is sufficient;
+  selection via core options dropdown sorted alphabetically.

-  The Y-ZOOM ROM (ng-lo.rom / 000-lo.lo) is a sprite zoom lookup table loaded
-  separately (src/memory.h:22, YZOOMROM_SIZE = 0x10000 = 65536 bytes). It is
-  optional but improves sprite scaling accuracy.
+  Y-ZOOM ROM (ng-lo.rom / 000-lo.lo) listed in .info but generated
+  algorithmically, never loaded from file (src/memory.cpp:223-253
+  generateYZoomData, CRC32 E09E253C). These are phantom .info entries.

-  All firmware entries are marked optional in the .info (any single valid BIOS
-  is sufficient). The core presents detected BIOSes as a dropdown in the core
-  options menu, sorted alphabetically by description.
-
-  BIOS ROM size: 524288 bytes (0x80000, src/memory.h:16).
-  Y-ZOOM ROM size: 65536 bytes (0x10000, src/memory.h:22).
+  .info firmware_count=12 but 2 are phantoms (Y-ZOOM), effective count=10.
+  .info lists uni-bioscd.rom as "Universe BIOS 3.2" but SHA1 matches
+  Universe BIOS 3.3 (confirmed by GitHub README).
