Abdessamad Derraz 463fca7e7d Regenerate database and update emulator profiles 
Regenerate database.json and update README counts/timestamps; add and normalize numerous BIOS entries and hashes. Key changes: update generated_at timestamp and system count (355→357) in README; add OpenBIOS / HLE fallback and additional aliases to beetle_psx, include beetle_psx core name and profiled_date update; add laseractive to ares systems; adjust atari800 systems and source_ref line numbers; mark dinothawr as a system and expand its note; update gsplus upstream/profile date, add apple-iie system and tweak source_refs; add pcsx2 core to lrps2; refresh mame profiled_date and add multiple systems and BIOS root sets. Miscellaneous script changes and other JSON normalization to reflect newly discovered/merged BIOS files.

# RetroBIOS
Complete BIOS and firmware packs for Batocera, BizHawk, EmuDeck, Lakka, Recalbox, RetroArch, RetroBat, RetroDECK, RetroPie, and RomM.
**7,245** verified files across **357** systems, ready to extract into your emulator's BIOS directory.
## Quick Install
Copy one command into your terminal:
```bash
# Linux / macOS / Steam Deck
curl -fsSL https://raw.githubusercontent.com/Abdess/retrobios/main/install.sh | sh
# Windows (PowerShell)
irm https://raw.githubusercontent.com/Abdess/retrobios/main/install.ps1 | iex
# Handheld (SD card mounted on PC)
curl -fsSL https://raw.githubusercontent.com/Abdess/retrobios/main/install.sh | sh -s -- --platform retroarch --dest /path/to/sdcard
```
The script auto-detects your platform, downloads only missing files, and verifies checksums.
## Download BIOS packs
Pick your platform, download the ZIP, extract to the BIOS path.

## Build your own pack
Clone the repo and generate packs for any platform, emulator, or system:
```bash
# Full platform pack
python scripts/generate_pack.py --platform retroarch --output-dir dist/
python scripts/generate_pack.py --platform batocera --output-dir dist/
# Single emulator or system
python scripts/generate_pack.py --emulator dolphin
python scripts/generate_pack.py --system sony-playstation-2
# List available emulators and systems
python scripts/generate_pack.py --list-emulators
python scripts/generate_pack.py --list-systems
# Verify your BIOS collection
python scripts/verify.py --all
python scripts/verify.py --platform batocera
python scripts/verify.py --emulator flycast
python scripts/verify.py --platform retroarch --verbose # emulator ground truth
```
Only dependency: Python 3 + `pyyaml`.
## Documentation site
The [documentation site](https://abdess.github.io/retrobios/) provides:
- **Per-platform pages** with file-by-file verification status and hashes
- **Per-emulator profiles** with source code references for every file
- **Per-system pages** showing which emulators and platforms cover each console
- **Gap analysis** identifying missing files and undeclared core requirements
- **Cross-reference** mapping files across 10 platforms and 328 emulators
## How it works
Documentation and metadata can drift from what emulators actually load.
To keep packs accurate, each file is checked against the emulator's source code.
1. **Read emulator source code** - trace every file the code loads, its expected hash and size
2. **Cross-reference with platforms** - match against what each platform declares
3. **Build packs** - include baseline files plus what each platform's cores need
4. **Verify** - run platform-native checks and emulator-level validation
