dcpu16 / dcpu16-py Goto Github PK

A Python implementation of Notch's DCPU-16.

See http://0x10c.com/doc/dcpu-16.txt for specification.

Notch apparently started doing a 6502 emulator first. Given I did one in
Python <https://github.com/jtauber/applepy> it only seems fitting I now
do a DCPU-16 implementation in Python too :-)


STATUS

Runs the example program successfully. Cycle times are not yet taken
into account but it otherwise should be feature-complete.

A dissassembler and assembler are also included.

./asm.py example.asm example.obj will assemble Notch's example to object code
./dcpu16.py example.obj will execute it (currently hard-coded to debug mode)
./disasm.py example.obj will disassemble the given object code

Note that the disassembler doesn't quite output in a format that can be
round-tripped back into the assembler as it annotates each line with a
memory offset.

I plan to work on a Forth implementation soon.

I'm also keen to find out how Notch plans I/O to work.


EXAMPLES

Now see https://github.com/jtauber/DCPU-16-Examples (almost my assembler and
emulator don't necessarily support everything there yet)
