bios/Sega/Triforce/.variants/segaboot.gcm was never a SegaBoot image:
its header reads "(C) 1999-2001 Nintendo" and it matches Redump's
"Triforce (ARCADE BOOTROM)". crediar's Dolphin fork reads the IPL from
GC/<region>/IPL_TRI.bin and SegaBoot from Triforce/segaboot.gcm, two
separate paths, so it moves to GC/USA/IPL_TRI.bin.
segaboot.gcm.e475c7dc is SegaBoot v3.11, the sha1 emulators/triforce.yml
already declared with no local file.
spec128.zip.1a524bfa is rebuilt from the FinalBurn Neo ZX Spectrum
recipe and roms already held, closing one of the pinned archives listed
as unobtainable.
