3c46a41351 Fix little-endian issue with IND output
Also change the ADDR label to emit a hex code, not a decimal code.

1abf0223c8 The value of PC by that point is correct.
Adding 2 skips us ahead farther than we should be going.

b21b48cac0 Fix a couple of issues...
1. The execute function should not be incrementing the PC register, as
this happens in other places.
2. The push_ and pop_stack functions were not considering that the data
should be in little-endian order.

e4049a6a11 Better info on each opcode sequence
Plus fix a display bug that showed the operand in the wrong order.

7c899122ad We should advance to the next byte in execution 2018-01-08 21:15:56 -06:00

a8bba409c3 Change 16-bit references to respect little-endianness
As the Apple II (or rather the 6502 chip) is little-endian, meaning the
least significant byte is the first byte you read going forward, rather
than the last byte.

01174b63dd The data in objstore_data was not in the correct order.
See also the change in tools/store-data; the system rom was first, when
the disk2 rom should have been first.

419b82faf1 Add missing tests for reset, set_memory
This also consciously ignores tests for free() (handled implicitly in
all teardowns) and run_loop (for which I don't have a good notion to
test right now).

ignored the LSB at $FFFD.

Things are getting a little hairy...at least, as to my own
comprehension. Documentation is a must.
