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: |
-  Fork of Snes9x ~2005, optimized for slow hardware.
-  NOT identical to snes9x — different firmware behavior.
+  Based on multiple snes9x forks (uosnes, snes9x2005), optimized for slow hardware.
+  All coprocessor data (DSP1-4, CX4, SuperFX, SA-1, SPC7110, OBC1) is HLE with
+  embedded ROM tables. No external coprocessor firmware needed.
+  BS-X BIOS loading controlled by core option chimerasnes_bsx_bios (default: skip).
+  retro_load_game_special() returns false (no subsystem support).
+  .info firmware_count absent (= 0), under-declares: code loads 2 files.
 
-  All coprocessor data is HLE with static ROM tables embedded:
-    DSP1: DSP1ROM[1024] in source/dsp1.c:6
-    DSP3: DSP3_DataROM[1024] in source/dsp3.c:7
-  No external DSP/ST/CX4 firmware files needed.
