FX-BMP has a variety of possible sizes, according to the technical documents.
Although 128KB was the only size marketed, the PC-FX BIOS supports 128KB, 256KB, 512KB, 1MB and 2MB sizes; all sizes below 1MB use a FAT12 filesystem, whereas 1MB and 2MB use a FAT16 filesystem.
As it may be useful/interesting to study these various sizes, this should be made to be configurable.
