INC r1 INC r1 INC r1 INC r1 INC r1 INC r1 # while decrementing R0 by 1 DEC r0 # until R0 is 0 (effectively 6x6) TEST r0, 7 #increment r0 by 4 INC r0 INC r0 INC r0 INC r0 # while decrementing R1 by 1 DEC r1 # until R1 is 0 (effectively 36x4) TEST r1, 15 R0 = 144, R1 = 0, R2 = 0, R3 = 0, R4 = 0 .. it helps if you know brainfuck ... :D hey.. solved the puzzle, actually it took me longer to make the emulator work than to actually write the code

R0 = 144, R1 = 0, R2 = 0, R3 = 0, R4 = 0

.. it helps if you know brainfuck … :D
