Abdessamad Derraz 58f3006d20 docs: add core_version, display_name to all 260 emulator profiles
Every profile now has:
- profiled_date: date of source code analysis
- core_version: version from libretro-core-info .info files
- display_name: human-readable name from .info files

260/260 profiles complete. 294/294 libretro cores covered.
Standalone emulators (cemu, rpcs3, xemu, vita3k) versioned manually.

notes: |
TGB Dual is a Game Boy / Game Boy Color emulator by GIGO and Hii with
link cable support for two Game Boy units side by side.
No BIOS or boot ROM files are required or supported. The core does not
call RETRO_ENVIRONMENT_GET_SYSTEM_DIRECTORY for firmware loading and does
not attempt to open any files from the system directory.
In cpu.cpp:57, the program counter is initialized to 0x100 (post-boot ROM
entry point), and cpu::reset() sets all registers to their post-boot
values directly (AF=0x01B0 for DMG, 0x11B0 for CGB). This means the
core completely bypasses the boot ROM sequence via HLE register setup.
The load_rom() path in libretro.cpp passes ROM data directly to the gb
class without any BIOS file concatenation or boot ROM mapping.
Supported extensions: gb, dmg, gbc, cgb, sgb.
Library version: v0.8.3.
