Lynx BIOS freezes on load

[rzumer]

The whole application stops responding when loading Lynx titles using the Handy core, while a BIOS file is present in the System directory. The file is named according to the libretro documentation for Handy (https://docs.libretro.com/library/handy/) and the MD5 hash used for my tests matches. When the file is absent, loading works as expected (because Handy provides a pseudo BIOS to load without a real one present).
