Missing 6309 instructions #44

Closed BGPierce closed 4 years ago

BGPierce commented 8 years ago

It has come to my attention that there are some 6309 instructions missing from the 6309 emulation in VCC. It would be nice to have the full 6309 implementation in VCC. I haven't actually seen problems with this that I know of, but I know some adventurous programmer will catch it.

I believe this to be a duplicate of BGPierce/VCC#37 .

Actually no... at least as for the nature of the bug itself. BGPierce/VCC#37 "may" be caused by the missing 6309 instructions, but ultimately, VCC should not crash on ANY bad instruction or memory read/write. The example of the crash you saw was just one example... I've crashed it may ways other than that one.

What instructions are actually missing?

BGPierce commented 7 years ago

Gary, I'm not sure which instructions are missing, but I do remember there being discussion on it one time, long ago on the coco3.com forum. Wes may know more about this than I do, but he seems to have disappeared for a bit.

Full list is now located in the new file in Docs/VCC-Notes.md. Also note there is a huge bunch that are listed as untested. Listing unimplemented instructions here for reference:

Fixed.
