feat: add emulator profiles and cross-reference engine (tier 2)
New two-tier architecture:
- Tier 1: Platform configs (what the UI checks) - unchanged
- Tier 2: Emulator profiles (what the code actually loads)
11 emulator profiles from source code analysis:
cemu, citra, dolphin, duckstation, flycast,
melonds, pcsx2, ppsspp, rpcs3, vita3k, xemu
Each profile documents every file the emulator loads with
source code references (file:line), hashes, and notes.
New scripts/cross_reference.py computes gaps between what
platforms declare and what emulators need.
Current gap: 200 undeclared files, 24 already in repo.
DuckStation alone recognizes 105 PS1/PS2 BIOS variants.
generate_pack.py gains --include-extras flag (future use).
_registry.yml maps platforms to their emulators.

Full HLE emulator. No Sony firmware or BIOS required.
|
|
|
|
|
All PSP kernel modules (flash0:/kd/*.prx) are reimplemented in C++.
|
|
|
|
|
Libretro core loads assets from system/PPSSPP/ via VFS.
|
|
|
|
|
Assets include replacement PGF fonts (18 files in flash0/font/),
|
|
|
|
|
game compatibility database (compat.ini), language mapping (langregion.ini),
|
|
|
|
|
and post-processing shaders (shaders/).
