The mod uses a custom assembly language. Each line of code represents one instruction.

Registers

Registers are internal memory slots used to store and manipulate data.

Register	Type	Description
A, B, C, D	General Purpose	Used for variables and arithmetic.
ports	Configuration	A bitmask used to set ports as Input (0) or Output (1).
PF, PB, PL, PR, PT, PD	I/O	Front, Back, Left, Right, Top, and Down ports.

Port Bitmask (`ports`)

The ports register uses a 4-bit or 6-bit binary value to define port direction. The bit order is typically: [Bottom][Top][Right][Left][Back][Front] Example: mov ports, 0010b sets the Back port as an output/active port for monitoring.

Instruction Set

Instruction	Syntax	Description
MOV	`mov dest, src`	Copies the value from source to destination.
ADD	`add dest, src`	Adds source to destination.
SUB	`sub dest, src`	Subtracts source from destination.
MUL / DIV	`mul dest, src`	Multiplies or divides destination by source.
CMP	`cmp val1, val2`	Compares two values and sets internal flags.
INC / DEC	`inc reg` / `dec reg`	Increases or decreases a register by 1.
JMP	`jmp label`	Jumps to a specific label in the code.
JZ / JNZ	`jz label`	Jump if Zero / Jump if Not Zero.
CALL / RET	`call label`	Calls a subroutine and returns.
NOP	`nop`	No Operation (waits for 1 tick).
SLEEP	`sleep`	Pauses execution until an external signal is received.
