The pin (1e0de94d) already loads Sega CD, 32X, ColecoVision and LaserActive firmware from the system directory, and the profile still described the earlier core with no BIOS at all. Each file now carries its code reference, required flag and build. The LaserActive player firmware (uPD78237, 64 KiB) is collected from the dump its author published.
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.
