4beff0bff8 Remember that we must obey little-endian order 2018-01-09 16:00:15 -06:00

42394fee80 Add new peripheral ROMs, plus a stub ROM 
...The latter being in the form of the zeropad file, 256 bytes long.

d7148b88bf Relative address was not being calculated correctly. 
The disassembler is using the correct approach, so I adapted it to the
execution code.

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
Peter Evans
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).

d9527db033 Retrieve the 16-bit PC address.

ignored the LSB at $FFFD.

c7aa9e9fc3 Resolver may be NULL; don't call if so 
This change also registers a default value for operand (0).
