notes: >
Community fork of Mednafen's Lynx module (itself based on Handy by
K. Wilkins) for libretro. Loads lynxboot.img from the system directory
at game load time (libretro.cpp:191). CRom constructor reads exactly
512 bytes (rom.cpp:50-78). 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 without the real boot
ROM. No hash validation is performed on the BIOS at load time.
The cart database in cart.cpp includes the BIOS CRC32 0x0d973c9d for
identification purposes, not validation.
Upstream Mednafen throws an exception if the BIOS is missing or
undersized; the libretro port silently degrades. Upstream supports
custom palette loading (lynx.pal); the libretro port does not.
