The LaserActive v1.05 variant read WONDER-MEGA BOOTROM 1.00W at 0x100, as No-Intro and TOSEC name it. It moves to the Mega CD tree and the catalogued v1.05 (md5 927df773) takes its place.
A copy under .variants/ exists to hold a content its primary does
not. 29 held bytes another file already carried, under a second or
third identity: msx.rom and MSX.ROM variants equal to
MSX_8020-20bios.rom, naomi2.zip.da79eca4 whose suffix named the
primary's sha1 rather than its own. dedup now removes such a copy,
keeping one when only variants hold the content. The LaserActive
PAC-S10 BIOS lived only under .variants/ while RetroBat names it
without a hash; it moves beside its siblings.
