feat: re-profile 40 emulators, harden CI workflows
profile emulators pd777 through tic80, add frozen snapshots (puae2021, snes9x2002/2005/2010, stella2014/2023). CI: replace github-script with gh CLI, add test execution, job-level permissions, propagate changed output, pin jsonschema.

# snes9x uses HLE for all coprocessors: DSP1-4, ST010, ST011, ST018, CX4.
|

# No external firmware files are needed for these chips - the emulation
|
||||
# logic and lookup tables are hardcoded in dsp1.cpp, dsp2.cpp, dsp3.cpp,
|

# dsp4.cpp, seta010.cpp, seta011.cpp, seta018.cpp, c4emu.cpp.

# Unlike bsnes, snes9x does NOT support LLE coprocessor firmware.
|

# It also does NOT support Super Game Boy (RETRO_GAME_TYPE_SUPER_GAME_BOY
|

# is defined but never loads a SGB BIOS or boot ROM).
|

#
|

# The only external BIOS files used are for Satellaview (BS-X) and

# Sufami Turbo, loaded by LoadBIOS() in libretro/libretro.cpp and

# BSX_LoadBIOS() in bsx.cpp.

Current snes9x. Loads BS-X.bin (tries BS-X.bios as fallback)
|

and STBIOS.bin via LoadBIOS() in libretro.cpp.
|
||||
Auto-detects Sufami Turbo carts (is_SufamiTurbo_Cart) and
|
||||
BS-X games (is_bsx) when loading via retro_load_game().
|
||||
Also handles retro_load_game_special() for multi-cart and
|
||||
subsystem types (RETRO_GAME_TYPE_BSX, RETRO_GAME_TYPE_SUFAMI_TURBO,
|
||||
RETRO_GAME_TYPE_MULTI_CART).

|

notes: |
|

Based on snes9x 1.52. Same BIOS loading as snes9x current.
|
||||
BSX_LoadBIOS() in src/bsx.c loads BS-X.bin (fallback BS-X.bios).
|

STBIOS.bin loaded in src/memmap.c for Sufami Turbo.

|

notes: |
|

Based on snes9x 1.43. Detects BS-X and Sufami Turbo ROM headers
|
||||
in source/memmap.c but has no LoadBIOS function - does not load
|
||||
external BIOS files. No firmware needed.

hle_only: true
|

notes: |
|

Same codebase as snes9x2005 with video enhancements.

|
||||
firmware_loading: false
|
||||
hle_only: true
|
||||
notes: |
|
||||
Based on snes9x 1.39 (PocketSNES). Minimal core for low-end
|
||||
devices. No BS-X, no Sufami Turbo, no external BIOS loading.
|
||||
No firmware needed.
|
||||
Loads BS-X.bin and STBIOS.bin via LoadBIOS() in libretro.cpp.
|
||||
BSX_LoadBIOS() in bsx.cpp tries BS-X.bios as fallback.
|
||||
Auto-detects Satellaview and Sufami Turbo carts on load.
|
||||
Subsystem support via retro_load_game_special() for
|
||||
RETRO_GAME_TYPE_BSX, RETRO_GAME_TYPE_SUFAMI_TURBO,
|
||||
RETRO_GAME_TYPE_MULTI_CART.

|

notes:
|
||||
coprocessor_hle: |
|
||||
All SNES coprocessor chips are emulated in software (HLE) across
|
||||
every snes9x variant. No external firmware files are needed for:
|
||||
- DSP1/DSP1B (dsp1.cpp, static DSP1ROM[1024] lookup table)
|
||||
- DSP2 (dsp2.cpp)
|
||||
- DSP3 (dsp3.cpp)
|
||||
- DSP4 (dsp4.cpp)
|
||||
- ST010 (seta010.cpp, static ST010_SinTable)
|
||||
- ST011 (seta011.cpp)
|
||||
- ST018 (seta018.cpp)
|
||||
- CX4/Cx4 (c4.cpp, c4emu.cpp, math-based HLE)
|
||||
This is the key difference from bsnes, which supports both HLE and
|
||||
LLE (with optional external firmware ROM files).
|
||||
sgb_status: |
|
||||
RETRO_GAME_TYPE_SUPER_GAME_BOY (0x104) is defined in libretro.cpp
|
||||
but no actual SGB emulation exists. No SGB BIOS or boot ROM is
|
||||
loaded or used by any snes9x variant.
|
||||
bsx_detection: |
|
||||
BS-X games are auto-detected by is_bsx() which checks for the
|
||||
"Satellaview BS-X" signature in the ROM header. When detected,
|
||||
the BIOS is loaded automatically without user intervention.
|
||||
sufami_detection: |
|
||||
Sufami Turbo carts are auto-detected by is_SufamiTurbo_Cart()
|
||||
which checks for "BANDAI SFC-ADX" at ROM offset 0 and absence
|
||||
of "SFC-ADX BACKUP" at offset 0x10 (which would indicate BIOS,
|
||||
not cart). Multi-cart support uses retro_load_game_special().
|
||||
All coprocessors are HLE (DSP1-4, ST010, ST011, ST018, CX4).
|
||||
No external firmware files needed. Lookup tables and math
|
||||
emulation hardcoded in dsp1-4.cpp, seta010-018.cpp, c4emu.cpp.
