Fork of Mednafen's Handy module for Atari Lynx emulation via libretro.
|
|
The core loads lynxboot.img from the system directory at game load time
|
|
(libretro.cpp:191). CRom constructor in rom.cpp reads exactly 512 bytes
|
|
from the file. If the file is missing or undersized, the ROM array is
|
|
filled with 0x88 (DEFAULT_ROM_CONTENTS) and the core continues without
|
|
error, but games will not boot correctly without the real boot ROM.
|
|
The cart database in cart.cpp identifies the BIOS by CRC32 0x0d973c9d
|
|
("[BIOS] Atari Lynx (USA, Europe)", size 512).
|
|
No hash validation is performed on the BIOS at load time.
|
|
Core options: lynx_rot_screen (screen rotation), lynx_pix_format
|
|
(pixel format), lynx_force_60hz (force 60Hz refresh).
|
|
ROM extensions: .lnx, .lyx, .bll, .o
