The SFIX (System FIX) ROM is a 64KiB or 128KiB ROM containing the default fix layer tileset embedded in most MVS boards.

It is used by the system ROM to display menus when no cartridges are inserted. It can be switched in or out with registers Reg.png REG_BRDFIX and Reg.png REG_CRTFIX.

The home system does not have an SFIX ROM.
