openMSX reads share/systemroms below OPENMSX_HOME or ~/.openMSX and
every filepool entry by SHA1. The profile paths drop RetroBat's
openmsx/ prefix and declare those directories and the filepool.
Batocera's config_directories reads the filepool lines its generator
writes, KNULLI reuses it. RetroBat records OPENMSX_HOME, RetroPie the
moveConfigDir of ~/.openMSX that its systemroms link lies in, and the
configure --prefix of xroar that its roms link lies in.
Batocera and KNULLI system ROMs move from openmsx/share/systemroms to
openmsx/, beside the files their own lists declare, RetroPie's to
BIOS/openmsx, the folder linked as share/systemroms.
