notes: |
|
|
bnes is a NES emulator based on byuu's bNES/higan v083 NES module, ported
|
|
to libretro by Ryphecha. It is a lightweight, accuracy-focused NES core.
|
|
|
|
The core loads cartridge data entirely through retro_load_game with
|
|
need_fullpath=false (libretro.cpp:129). ROM data is passed as a memory
|
|
buffer and parsed by Cartridge::load (cartridge.cpp:18-31), which detects
|
|
iNES headers (16-byte offset) and delegates to Board::load for mapper setup.
|
|
|
|
The PPU generates its palette from a hardcoded color table in libretro.cpp
|
|
(lines 20-37) with emphasis factor tables. No external palette file is loaded.
|
|
|
|
System::init (system.cpp:62-66) only sets up the interface pointer and
|
|
default input devices. No system ROM, BIOS, or firmware is loaded at any
|
|
stage of initialization or cartridge loading.
|
|
|
|
The core does not call RETRO_ENVIRONMENT_GET_SYSTEM_DIRECTORY and has no
|
|
file I/O for BIOS or firmware. FDS (Famicom Disk System) is not supported,
|
|
so disksys.rom is not needed.
|
|
|
|
No external BIOS or firmware files are needed.
