Once loading is complete, the game executes only from RAM, thereby reducing mechanical wear on the GD-ROM drive. In operation, the Naomi GD-ROM is read only once at system power up, loading the disc's contents to the DIMM Board RAM. The Dreamcast reads game data from GD-ROM optical disc, while the NAOMI arcade board features 168 MB of solid-state ROMs or GD-ROMs using a custom DIMM board and GD-ROM drive. The other key difference between NAOMI and Dreamcast lies in the game media. Multiple NAOMI boards can be 'stacked' together to improve graphics performance, or to support multiple-monitor output. NAOMI has twice as much system memory, twice as much video memory, and 4X as much sound memory.
