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.

+  Mu emulates Palm m500, Palm m515, and (with EMU_SUPPORT_PALM_OS5)
+  Tungsten T3. A Palm OS ROM dump is required. The core selects the
+  ROM filename based on the "OS Version" core option:
     Palm m500 / Palm OS 4.0   -> palmos40-en-m500.rom
     Palm m515 / Palm OS 4.1   -> palmos41-en-m515.rom  (default)
     Tungsten T3 / Palm OS 5.2 -> palmos52-en-t3.rom
     Tungsten T3 / Palm OS 6.0 -> palmos60-en-t3.rom
 
-  ROM path construction: retro_load_game() joins
-  RETRO_ENVIRONMENT_GET_SYSTEM_DIRECTORY + "/" + osVersion + ".rom".
-
-  The bootloader (bootloader-dbvz.rom) is optional. It contains the
-  MC68VZ328 UART bootloader and is only relevant for m500/m515 devices.
-  For the Tungsten T3 it is ignored even if present.
-
-  The m500/m515 ROM is loaded into a 4 MB region (M5XX_ROM_SIZE),
-  padded with 0x00 if smaller, and byte-swapped on little-endian hosts.
-  The Tungsten T3 ROM maps into a 16 MB region (TUNGSTEN_T3_ROM_SIZE).
-
-  The core also supports no-game mode (supports_no_game = true). Without
-  content, it boots the standard Palm OS desktop from the ROM.
+  ROM path: RETRO_ENVIRONMENT_GET_SYSTEM_DIRECTORY + "/" + osVersion + ".rom".
+  No hash or size validation; the code reads whatever file is present.
+  The bootloader is optional and ignored for Tungsten T3.
+  Supports no-game mode (boots Palm OS desktop from ROM without content).
