    Problem is that the entire multiplication program is now offset from the ROM slot by one pixel and doesn't align. So I can't edit the program yet.

    Ahk. Also I updated the processor slightly. Instructions are now 25 bits long. It's explained in the thread. All you would need to do is drag the last 4 bits in your program over 1 place to the right. (since I have now designated 5 bits to the last group of bits).

    K, everything is working fine until the last set of bit shifts for the last bit of the second operand. I think it should work after I fix it.

    Yeah, I actually intended on righting B to 0 to declare a logic structure resembling If(A > B(0)){A = OP1; A * 2^n; RAM3 = A;}else{RAM3 = 0;}

    Ok I went all the way up to line 33, and every single instruction worked perfectly. So I think fixing the IF EQUAL solved most of the problem. I am guessing you were intentionally clearing B by not giving it a value? Also near the end of the program, there are 2 instructions telling the processor to add, but there is no destination (C/RAM)

    Found another problem with the IF EQUAL. It wouldn't work if B was 0. I fixed this, so now the 8 instruction works fine too, and it jumps to line 11.

    I noticed on line 7 you attempted ROM -> B. But you didn't include a value to put in B.

    Ok I am going through your program instruction by instruction. First 5 worked fine (C ended up getting 1), going through the rest now.

    I'll probably find the problem before then. Looking now. Also I just realized I broke the IF again when I fixed the JUMP. Gonna have to fix that again quickly lol.
