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: |
OpenTyrian is a source port of the DOS vertical scrolling shooter Tyrian,
ported to libretro. It loads the Tyrian 2.1 freeware game data directly.
Tyrian 1.x, 2.0, and Tyrian 2000 data files are NOT compatible.
The core's .info file sets supports_no_game = true. The core locates the
data directory by probing for tyrian1.lvl in several paths (file.c:33-58):
1. custom_data_dir (set via --data= CLI argument, params.c:120)
2. TYRIAN_DIR (compile-time constant, Makefile:5-8)
3. "data" (relative subdirectory)
4. "." (current working directory)
The first path containing tyrian1.lvl wins.
On startup (opentyr.c:270-388), the core:
- Scans for episodes by checking tyrian1.lvl through tyrian5.lvl
(episodes.c:270-277)
- Loads palette data from palette.dat (palette.c:45)
- Loads main shape tables from tyrian.shp (sprite.c:669-722, 12 sprite
banks packed in one file: fonts, interface, option sprites, game sprites,
weapon sprites, etc.)
- Loads sound effects from tyrian.snd and voice samples from voices.snd
(nortsong.c:112-134, opentyr.c:333)
- Loads music from music.mus (loudness.c:196)
- Loads help/item data from tyrian.hdt (helptext.c:184, episodes.c:60)
- Loads picture data from tyrian.pic (picload.c:32)
- Loads credits from tyrian.cdt (mainint.c:2002)
Each episode loads additional files dynamically (episodes.c:261-263):
- tyrianN.lvl (level data, N=1-5)
- levelsN.dat (episode level definitions)
- cubetxtN.dat (datacube text for story mode)
The game engine also loads shape files on demand:
- shapesX.dat where X is a character from a 34-entry lookup table
(lvlmast.c:23-27, tyrian2.c:3079). Characters used:
2,4,7,8,A,B,C,D,E,F,G,H,I,J,K,L,M,N,O,P,Q,R,S,T,U,5,#,V,0,@,3,^,9
- newshX.shp loaded via JE_loadCompShapes (sprite.c:469-481) using the
same character set plus '~' for destruct mode (destruct.c:569) and
'1' for arrow/mouse cursor sprites (mainint.c:493,884,1462) and
'6' for explosion sprites (tyrian2.c:771)
Additional optional files:
- tyrianc.shp and voicesc.snd for Christmas mode (opentyr.c:301-309)
- tyrend.anm for ending animation (tyrian2.c:2473)
- tshp2.pcx loaded during gameplay (tyrian2.c:2757, pcxload.c:25)
- estsc.shp for ending sequence sprites (mainint.c:1995)
- demo.1 through demo.5 for demo playback (mainint.c:1781-1786)
All filenames must be lowercase on case-sensitive filesystems. The repo
includes lower-script.sh for batch renaming.
The Tyrian 2.1 freeware data is available at:
https://camanis.net/tyrian/tyrian21.zip
No separate BIOS or firmware is needed. The freeware game data set is the
sole system requirement.
