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