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.

-  Meteor is a Game Boy Advance emulator by Philippe Daouadi (2009-2011).
-
-  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()
-  function only loads the ROM via LoadRom().
-
-  HLE SWI coverage: SoftReset (0x00), RegisterRamReset (0x01), Halt (0x02),
-  IntrWait (0x04), VBlankIntrWait (0x05), Div (0x06), DivArm (0x07),
-  Sqrt (0x08), ArcTan (0x09), ArcTan2 (0x0A), CpuSet (0x0B),
-  CpuFastSet (0x0C), BgAffineSet (0x0E), ObjAffineSet (0x0F),
-  LZ77UnCompWram (0x11), LZ77UnCompVram (0x12), HuffUnComp (0x13),
-  RLUnCompWram (0x14), RLUnCompVram (0x15).
-
-  Missing from HLE: Stop (0x03), BitUnPack (0x10), Diff8bitUnFilter (0x16-0x17),
-  Diff16bitUnFilter (0x18), SoundBias (0x19), SoundDriverInit (0x1A-0x1F),
-  MidiKey2Freq (0x1F), SoundDriverVSyncOff/On (0x28-0x29), GetBiosChecksum (0x0D).
-
-  The BIOS memory region (0x00000000-0x00003FFF, 16 KB) is allocated only if
-  LoadBios() is called. Memory reads to this region return BIOS protection values
-  (0x0E for 8-bit, 0xF00E for 16-bit, 0xE1B0F00E for 32-bit) when no BIOS is
-  loaded and PC is outside the BIOS area.
-
-  Bios000h() (entry point) initializes stack pointers and jumps to 0x08000004,
-  matching real GBA hardware boot sequence. In the libretro port, retro_reset()
-  resets all units except BIOS and ROM memory.

       Full HLE BIOS. The libretro port never loads an external BIOS file.
-      Cpu::SoftwareInterrupt() checks HasBios() -- if false (always in libretro),
-      SWI calls are routed to C++ reimplementations. If a real BIOS were loaded
-      (standalone only), execution would go through the actual BIOS ROM code via
-      SoftwareInterrupt() -> branch to 0x08.
