#155 SD2IEC Emulation

Ingo Korb
new Device (Drives)

Please consider adding SD2IEC emulation. The native file system emulation does not provide a couple of key areas of compatibility that non-trivial uses of VICE requires:

1) REL file support. SD2IEC does this in native folders.
2) Partitions support. SD2IEC does this on any device that is hooked up, including SD-Cards
3) Real Time Clock support. Though not implemented on any CURRENT SD2IEC design, the firmware supports RTC access via the CMD standard. Software that supports the CMD clock standard (such as GEOS) would benefit from this availability.

Please don't just dismiss these issues as non-issues. There are many things that programmers want to test that are available on many large devices, such as partitions and REL files, that simply cannot be debugged and replicated in VICE today.

    all i can say to that is:

    a) NO. sd2iec is an aftermarket non commodore device and as such the chance of including emulation for it in VICE is pretty slim. there is also very little reason for doing it because
    b) the things you are listing could be added to the virtual filesystem, making it compatible to the CMD standard (and sd2iec).

    so, as said countless times before, the solution is to add these features to the virtual filesystem. (although i am not sure how partitions would come into play there)

    that said, supplying explicit test cases for the mentioned scenarious (meaning test programs including their sourcecode, for inclusion in the test repository) would be a good start to make it happen :)

    btw: can't you test the mentioned features using either FD2000 or FD4000 emulation?
