Technical notes

Neo Geo subset of FinalBurn Neo, current codebase (not frozen). Built with SUBSET=neogeo, includes only d_neogeo.cpp drivers. Exists for platforms that cannot run the full FBNeo core.

Neo Geo games reference "neogeo" as parent ROM set. The BIOS ZIP must be alongside game ZIPs or in system_dir/fbneo/. Search order (libretro.cpp:930-1083): 1. {system_dir}/fbneo/patched/{romName} 2. {rom_dir}/{romName} 3. {rom_dir}/{arcade|consoles}/{romName} 4. {system_dir}/fbneo/{romName} 5. {system_dir}/fbneo/{arcade|consoles}/{romName} 6. {system_dir}/{romName} 7. directories listed in rom_path.opt, plain then per-type subdirectories

neogeo.zip contains multiple selectable 68K BIOS variants (MVS, AES, Universe BIOS). One 68K BIOS active at a time (dipswitch). Z80 BIOS, fix tiles, and zoom table always required.

Neo Geo CDZ uses neocdz.zip with parent "neogeo". CD/CDZ BIOS plus zoom table.
