Find Your Dog

Lots to be done still.  Submitting before deadline so I have _something_ visible by the time things close.

Pushing control / command next to things with a CPU will let you edit the CPU's microcode.  The CPU has 256 bytes of memory, no registers, aside from a program counter, and has 16 instructions.

A star next to an operand means 'dereference', or 'read the memory from this location before applying the operation'.

ADD 0x1 0x2 0x3 means 'Add the values 1 and 2 and store it in address 3.'

ADD *0x1 0x2 0x3 means 'Read the memory at address 0x1 and add 2, then store it in address three.'

ADD 0x1 0x2 *0x3 means 'Add the values 1 and 2, then read the address at 0x3 and store it there.'

Internally all opcodes are basically four bytes.

The full instruction list:

Operation	Number of Instructions	Description
ADD	3	Add the first and second operands.  Store at the third.
SUB	3
MUL	3
DIV	3
MOD	3
AND	3
OR	3
XOR	3
NOT	2
MOV	2	Fake instruction that gets rewritten to OR OP0 0x0 OP1.  Useful for loading and moving data. Example: MOV 0x12 0x34 will move the literal 0x12 into the address 0x34.
JE	3	JUMP if OP0 and OP1 are equal.
JG	3	JUMP if OP0 > OP1.
SPC	1	Store program counter.  Can be used to fake subroutines.
JMP	1	Fake instruction that gets rewritten to JE 0x0 0x0 OP0
