NOTE: These are MAME "Virtual Machines." These virtual machines are ROM-specific but contain address space information (memory maps) that may be useful when debugging hardware. There may be descrencies between MAME's definition of the hardware, and actual hardware. Information is provided for reference only. THERE ARE NO ROMS ANYWHERE ON THIS WEB SITE.

NOTE: These are the "ROM Regions" defined in the MAME "Virtual Machine." Usually these correspond to actual CPUs or Sound CPUs. Occasionally they will not. Occasionally they will be wrong, or they will not be mappable locations. Paging is usually handled through a software "hack" and not represented in this map.
9010A: Refers to the Fluke 9010A Signature Analysis algorithm. You should independently confirm these signature numbers before using. Different ROM versions will have different signatures.

Emulated CPUs:
