"""PC-88 ROMs live in the PC-88 folder.

Sixteen ROMs that only quasi88 reads (N88EXT0-3, N88KNJ1, N88SUB, the n88
set, the disk subsystem ROM, pc88.rom) were stored under bios/NEC/PC-98,
and the site linked the nec-pc-88 system to the PC-98 page. A file in the
PC-98 folder must have a reader whose systems include the PC-98, or be one
