feat: re-profile 40 emulators from fbalpha2012 to holani

batch re-profiled beetle, holani, kronos, mame variants, mednafen
cores with upstream verification. beetle_pce, mame, mame2010 excluded
(regressions detected, need manual review).

notes: |
Beetle NGP is a fork of Mednafen's NeoPop module for Neo Geo Pocket
and Neo Geo Pocket Color emulation via libretro.
No external BIOS or firmware files are required. The core uses a
built-in High-Level Emulation (HLE) BIOS that is constructed at
runtime by bios_install() in mednafen/ngp/bios.c.
The HLE BIOS populates a 64KB array (ngpc_bios[0x10000]) with:
- A system call vector table at 0xFE00 (27 entries covering
clock, RTC, interrupts, font, flash read/write, comms)
- Each vector target contains an iBIOSHLE instruction (opcode 0x1F)
that traps into biosHLE.c for high-level handling
- A built-in system font (2048 bytes at 0x8DCF)
- A default interrupt handler (RETI at 0x23DF)
- An infinite loop at 0xFFFE as the idle entry point
The TLCS-900h CPU (main) and Z80 (sound) are both emulated in
software. Flash memory for game saves is handled internally via
flash.c without needing a separate firmware dump.
The only core option is ngp_language (english/japanese), which
controls the language flag passed to games. It does not affect
BIOS loading.
ROM extensions: .ngp, .ngc, .ngpc, .npc
Libretro port of Mednafen's NeoPop module (originally by neopop_uk).
HLE BIOS only, constructed at runtime by bios_install() in
mednafen/ngp/bios.c. No external BIOS or firmware files loaded.
Upstream Mednafen also uses HLE only (Documentation/ngp.html:
"BIOS is HLE'd"). The only core option is ngp_language
(english/japanese).
