+emulator: RACE (Neo Geo Pocket)
+type: libretro
+source: "https://github.com/libretro/RACE"
+systems: [snk-ngp, snk-ngpc]
+
+notes: |
+  RACE is a Neo Geo Pocket and Neo Geo Pocket Color emulator, originally
+  developed for PSP (forked from Akop Karapetyan's port), adapted for
+  libretro.
+
+  No external BIOS files are required. The core contains dead code in
+  race-memory.c that would load "NPBIOS.BIN" (64KB, loaded into cpurom
+  via filestream_open), but it is compiled out with #if 0 and loadBIOS()
+  unconditionally returns 0. The comment explains: "Using a real bios
+  file causes nothing but issues" and references Card Fighters' Clash
+  Test Mode as a known failure.
+
+  Instead, the core uses a software HLE approach:
+  - A built-in koyote_bin memory dump (RAM state from a real console
+    post-boot) is copied into mainram at startup
+  - A fake SWI jump table is constructed at cpurom[0xE000] using the
+    TLCS-900H 0x1A (reg) dummy opcode to trap BIOS calls
+  - doBios() in tlcs900h.c handles 33 BIOS functions in software:
+    shutdown, clock speed, RTC, screen mode, font rendering, flash
+    read/write, communication, and sound control
+  - Interrupt vectors are set up at cpurom[0xFF00] and interrupt
+    handler code at cpurom[0xF800]
+  - CPU RAM defaults (interrupt priorities, timers) are loaded from
+    the ngpcpuram[256] table
+
+  The Z80 sound CPU is emulated in software (cz80 or DrZ80 backend).
+  Flash memory for game saves is handled internally by flash.c.
+
+  The only core option affecting system behavior is ngp_language
+  (english/japanese), which sets a RAM flag at 0x6F87.
+
+  ROM extensions: .ngp, .ngc, .ngpc, .npc

+    notes: |
+      loadBIOS() is wrapped in #if 0 and always returns 0.
+      Even if re-enabled, the realBIOSloaded=1 path has known
+      compatibility issues (e.g. Puzzle Bobble fails to boot).
+      The HLE path is the only functional code path.
