The BIOS search dropped the arcade and consoles subdirectories under
both the rom directory and system/fbneo. Seven places to put a BIOS ZIP
became four, and both profiles still documented the old list, which is
the kind of thing a user follows.
fbneo's gba_bios.bin also cited a line in the middle of a battery
allocation; its RomDesc entry, which carries the name and the crc32, is
at 538.
Closes#43
FBNeo and Kronos expect BIOS archives in core-specific subdirectories
(system/fbneo/, system/kronos/). RetroArch firmware check uses .info
paths which include these prefixes, so files at root show as Missing.
Add archive_prefix field to emulator profiles. The pack code now places
archive copies in the prefixed subdirectory while keeping root copies
for cores that expect them there (e.g. Geolith for neogeo.zip).
trackball BIOS (236-bios.sp1, 236-bios_japan_hack.sp1) for irrmaze,
PCB BIOS (sp-4x.sp1, spj.sp1) for ms5pcb/svcpcb/kf2k3pcb. all carry
BRF_ESS flag in d_neogeo.cpp, verified against source.
