The Horizon Ramdisk 4000 can be emulated within MESS/MAME up to 16MiB of SRAM. The emulation will respond to the equivalent speed of the RAM disk on actual hardware.

	~~'''Note''':~~ The ~~directory is usually classified by the current machine type being emulated~~. ~~If you use the European version, your directory will be ''nvram/ti99_4ae''~~.		The following installation process was created using MAME0176b 64bit and ROS version 8.32e.

	~~This process was created using MAME0176b 64bit and ROS version 8.32e.~~		== Storage ==

	'''~~Note~~''': If ~~using ROS 8.14f or earlier~~, ~~sector sizes~~ will be ~~limited to 1600~~. ~~ROS 8~~.32 and ~~higher allows~~ for ~~3200 sectors per disk~~.		The contents of the RAM Disk is saved in the '''nvram/ti99_4a''' subdirectory of your MAME base directory. Windows OS use backslashes for the path, e.g. ''C:\mess\nvram\ti99_4a''.

			The directory is classified by the current machine type being emulated. If you use the European version, your directory will be ''nvram/ti99_4ae''. You can change the NVRAM subdirectory name via the ''nvram_directory'' property in the mame.ini configuration file; the default is ''nvram''.

			The file names in the NVRAM folder are derived from the slot where they are plugged in, and from the device where they are used. If your Horizon Ramdisk is located in slot 3, the file name is ''peb_slot3_horizon''. You can safely exchange the nvram files between different cards, installations, or you can send them to other people using MAME for TI emulation.
