Generic RAM/ROM Expansion possible?
Hello Toni,
after experimenting with the CDTV-Extension SRAM 128KB and reading about Kick-Flash Projects (i.e. http://eab.abime.net/showthread.php?t=94108) and 1MB-Kickstarts comes my question: Is it possible to integrate a generic RAM/ROM-Expansion with selectable size and address plus a possibility to preload that memoryarea (like a ROM-File for a HD-Controller or a freezer)? This would make development for such things a lot easier. |

User configurable (autoconfig or hardwired) RAM board is already possible using GUI.
ROM or RAM with data loaded from file is not (yet?) supported but it would be easy to add (would require config file editing, path pointing to file that gets loaded, not needed in GUI). |

fastmem/z3mem_options=filesize=X,fileoffset=Y,offset=Z,file=<path>,readonly X = Number of bytes to load (0 = all or size of RAM if file is larger). Y = File byte offset. Z = RAM byte offset relative to start address of RAM. readonly = obvious. (may not work in JIT mode) Path is mandatory, other entries default to zero. Append to end of fastmem_options if it already exists. Special characters must be escapted (\ = \\) in path. Load and save the config to see if escaping was correct. Thanks for noticing that (at least beginning of) hardware/driver development can be much easier when using emulation |
