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: >
   Region-based BIOS selection: the core picks JP/NA/EU firmware based on disc region.
   SHA1 validated with warning on mismatch (does not block loading).
+  SHA1 and alternate filenames sourced from MAME psx.cpp (libretro.cpp:184).
   Override option allows using PSP or PS3 extracted PS1 BIOS as region-free alternative.
-  "Skip BIOS" option exists but causes compatibility issues (PAL copy protection, Saga Frontier).
-  Alternate filenames are case variants and model aliases for the same image.
-  Comment in source references MAME psx.cpp as hash source.
+  "Skip BIOS" option patches BIOS ROM but causes compatibility issues.
+  Upstream Mednafen loads the same 3 region BIOS; override BIOS are libretro additions.
