Update DB timestamp; add ti99sim emulator

Bump database.json generated_at timestamp and add a new emulator metadata file emulators/ti99sim.yml. The new YAML registers the TI-99/Sim standalone emulator (ti99sim) with system info, core version, notes on ROM handling, and multiple required/optional ROM entries (with SHA1s, sizes and validation notes) for TI-99/4A support.
feat: add ROM_OS_B_NTSC and fs-5500_disk.rom, fix retrodeck

 notes: |
-  Vita3K requires the official PS Vita firmware (PSVUPDAT.PUP) from Sony for full
-  compatibility. The firmware is decrypted using SCE keys and extracted into four
-  partition images: os0 (kernel), vs0 (system), sa0 (assets), pd0 (data).
-
-  The most important firmware components are:
-  1. vs0/sys/external/*.suprx - Firmware modules loaded by games
-  2. sa0/data/font/pvf/*.pvf - System fonts (ltn0.pvf is checked at startup)
-  3. vs0/data/internal/ - LiveArea resources and default themes
-
-  Vita3K uses a hybrid LLE/HLE approach:
-  - Some modules (libc, libSceFt2, libpvf, libcdlg) are always loaded from firmware (LLE)
-  - Others can be toggled between LLE and HLE per module via settings
-  - Without firmware, many games will fail to load required modules
-
-  The module loading path is: first check app0:sce_module/{name}.suprx (game-bundled),
-  then fall back to vs0:sys/external/{name}.suprx (firmware). This allows games to
-  ship their own module versions.
-
-  CLI firmware install: vita3k --firmware /path/to/PSVUPDAT.PUP
-  GUI: File > Install Firmware
-
-  Vita3K does not have a libretro core. It is standalone only.
+  Standalone PS Vita emulator. No libretro core.
+  Firmware installed via File > Install Firmware or CLI --firmware flag.
+  PUP files validated by SCEUF magic header only (pup.cpp:119), no hash check.
+  After install, four partitions are extracted:
+    os0 (FAT, kernel modules), vs0 (FAT, system modules/apps),
+    sa0 (FAT, fonts), pd0 (exFAT, system data/BGM).
+  Module loading: app0:sce_module/{name}.suprx (game-bundled) then
+  vs0:sys/external/{name}.suprx (firmware). Auto-LLE modules include
+  libhttp, libssl, libult, libsas, libpgf, libfios2, libsystemgesture,
+  libSceXml, libSceSqlite, librudp, libatrac, libface, libsmart,
+  libsceavplayer, libSceJson, and more (load_module.cpp:142-161).
+  A third optional preinst firmware PUP (pd0 partition: system BGM, resources)
+  is available from Sony but not commonly required for game compatibility.

The new YAML registers the TI-99/Sim standalone emulator (ti99sim) with system info, core version, notes on ROM handling, and multiple required/optional ROM entries (with SHA1s, sizes and validation notes) for TI-99/4A support.	2026-03-29 23:33:12 +02:00

Remove ROM_400/800_CUSTOM from retrodeck.yml (config slot key with forward slash in name, not a real file).	2026-03-29 23:23:52 +02:00

Abdessamad Derraz	0c5cde83e1	Add TRS-80, RX-78, Sega AI entries; refactor tools Add many MAME/MESS BIOS entries (TRS-80 family, Bandai RX-78, Sega AI) and update docs/navigation counts (README, mkdocs). Remove empty supplemental file references from database.json and update generated timestamps and totals. Harden and refactor tooling: add MAX_RESPONSE_SIZE limited reader in base_scraper, make target scrapers an abstract base, narrow exception handling in the Batocera targets parser, and switch generate_pack.py and verify.py to use build_target_cores_cache (simplifies target config loading and error handling). verify.py also loads supplemental cross-reference names and accepts them through verify_platform. Update tests to import from updated modules (validation/truth). Misc: small bugfix for case-insensitive path conflict check.	2026-03-29 23:04:30 +02:00

Add Funtech Super A'Can BIOS entries (supracan.zip and umc6650.zip) with ROM contents to mamemess. Simplify and condense Vita3K emulator profile (rename fields, update profiled_date, add PSVUPDAT.PUP and optional PSP2UPDAT.PUP file entries, and clarify install/partition behavior). Bump database generated_at timestamp and add a system alias mapping "psvita" -> "sony-playstation-vita" in scripts/common.py.	2026-03-29 22:51:30 +02:00
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.	2026-03-29 22:41:01 +02:00
