I'm not actively working on it at the moment, so no objections here.

Here is my latest patch for this, against svn rev 39973. Converted from PET PIA to MC6821 core, and fixed the issue with kernel mapping. I also found the problem with my test program (there was an internal "fast load" setting that was inadvertently enabled; after staring at the IEEE trace logs long enough i eventually noticed the M-W commands that were confusing the SFD-1001 drive emulation :) The only remaining to-do item would be to ensure the Slot 0 passthrough works with other cartridges sanely....

Found a fairly major issue (likely the cause of Querino's issue) - when the kernel is swapped out, reads are still returning ROM data instead of RAM. Working on fixing that. I switched the PIA from piacore to mc6821core and that seems to work fine, apart from the kernel RAM read problem.

Will fix that shortly. The only other major to-do item i have for this feature is switching the implementation from piacore to mc6821core, but that could be done as a separate patch if you prefer since it "works" as is.

Added the missing option/resource docs and added a note to the IEEE interface section now that there are two options :) This patch goes on top of the previous 39929 patch.

Updated diff against svn 39929. Fixed the problem with port0 and having the interface enabled at startup. Added the new enable and file options to the SDL menus. Querino, some programs are not compatible with the IEEE Flash kernal, With the real interface, I'd flip the first switch to disable it and reset the computer, and it would revert to the standard kernal (simulate in VICE by turning it off). But it's possible that there is something still not quite right. For example, Stereo SIDPlayer runs...

PATCH: C64: Load drive resources after cart resources

Here is my first pass work-in-progress that incorporates the slot0 move. This works as long as the Flash cart is not enabled at startup. Still working to track down how to fix that (the problem seems to be related to not getting the ieeeflash64_rom array populated in that circumstance, unlike post-startup). This is a full diff from svn 39888 (so it replaces the original patch).
