batch re-profiled beetle, holani, kronos, mame variants, mednafen
cores with upstream verification. beetle_pce, mame, mame2010 excluded
(regressions detected, need manual review).

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
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.
