feat: re-profile 37 emulators with upstream verification

source-verified core_classification, upstream URLs, validation fields,
and hle_fallback flags. trimmed verbose notes. removed phantom files
(azahar boot9/sector0x96). added bsnes2014 variant profiles.

 notes: |
-  bsnes C++98 is bsnes v085 downgraded to C++98 for old compilers.
+  Frozen snapshot of bsnes v085 downgraded to C++98 for old compilers (PS3).
   Performance profile only. is_experimental=true.
 
-  Firmware loading differs from newer bsnes versions:
-  - NEC DSP (dsp1/2/3/4) and Hitachi DSP (cx4) firmware loaded from
-    the SAME DIRECTORY as the ROM, not from system_dir.
-  - Path: dir(interface->path(Slot::Base, ".dsp")) + firmware_name
-    ref: snes/cartridge/markup.cpp:231
-  - interface->path() returns basename + hint
-    ref: snes/libretro/libretro.cpp path() method
-  - Firmware name comes from the game's XML/BML markup (root["firmware"])
-    NOT fixed names like dsp1.program.rom
-  - Files are COMBINED (program+data in one file), not split
-    ref: snes/cartridge/markup.cpp:243-244 reads promsize*3 + dromsize*2
+  NEC DSP and Hitachi DSP firmware loaded from the ROM directory, not
+  system_dir. Path: dir(interface->path(Slot::Base, ".dsp")) + firmware_name
+  from game XML markup. interface->path() returns ROM basename + hint.
+  ref: snes/cartridge/markup.cpp parse_markup_necdsp, parse_markup_hitachidsp
+  ref: snes/libretro/libretro.cpp Interface::path()
 
-  .info has firmware_count=0 because firmware is loaded from ROM dir,
-  not from system_dir — RetroArch can't pre-populate them.
+  RETRO_ENVIRONMENT_GET_SYSTEM_DIRECTORY is never called.
+  No file I/O targets system_dir anywhere in the codebase.
 
-  The core warns "NEC DSP firmware X is missing" if not found but
-  continues without the coprocessor (games using it won't work).
+  Core continues without DSP firmware but coprocessor games won't function.
+
+exclusion_note: >
+  firmware_count=0 in .info is correct. DSP firmware (NEC uPD7725/uPD96050,
+  Hitachi CX4) is loaded from the ROM directory via game XML markup, not from
+  system_dir. RetroArch cannot pre-populate firmware in the ROM directory.
+  Upstream byuu.org is defunct; this libretro port is the preserved v085 code.
