- Added profiled_date field to all 204 existing profiles for update tracking - Created 56 alias profiles for cores that share BIOS with a parent (e.g., mednafen_psx -> beetle_psx, fbalpha2012 -> fbneo) 260 total profiles covering all 294 libretro cores (204 unique + 56 alias).

Play! is a full HLE (High-Level Emulation) PS2 emulator. It does not load or
|
|
require any real PS2 BIOS dump. The LoadBIOS() function in Ee_SubSystem.cpp
|
|
(which would read ./vfs/rom0/scph10000.bin) is commented out in PS2VM.cpp:ResetVM().
|

# No BIOS files required.

# IOP modules (rom0:SIO2MAN, rom0:PADMAN, rom0:MCMAN, rom0:MCSERV, etc.)
|
|
# are all replaced by HLE implementations in Source/iop/IopBios.cpp.
|
|
# The EE kernel/OS is reimplemented in Source/ee/PS2OS.cpp.

notes: |
|
|
Play! does not require any PS2 BIOS files. Unlike PCSX2, it uses High-Level
|
|
Emulation to reimplement the PS2 kernel, IOP BIOS modules, and system services
|
|
entirely in C++.
|
|
|
|
Key HLE components:
|
|
- EE kernel: Source/ee/PS2OS.cpp (handles BootFromCDROM, BootFromFile, syscalls)
|
|
- IOP BIOS: Source/iop/IopBios.cpp (HLE modules for rom0:PADMAN, MCMAN, MCSERV, etc.)
|
|
- No rom0/rom1/erom files are loaded at runtime
|
|
|
|
The legacy LoadBIOS() function in Source/ee/Ee_SubSystem.cpp references
|
|
"./vfs/rom0/scph10000.bin" but this call is commented out in PS2VM::ResetVM()
|
|
and has no effect on emulation.
|
|
|
|
mc2_ings.ico is not referenced anywhere in Play! source code. That file is
|
|
specific to PCSX2's memory card icon handling, not Play!.
|
|
|
|
The libretro core supports: .elf, .iso, .cso, .isz, .bin disc images.
|
|
Extensions handled in main_libretro.cpp:retro_get_system_info().
