Alright, Enough said. I FINALLY got the menu working and now I can start creating sprites for the actual game now!
HoMM: [==--------] Project 'resumed': I'm suffering overwhelming new ideas being popped up in my dreams :PtiDE: [----------] Explored and understood the main part of the code: just started writing a Tokenizer.

First, M>N will be 1 if M (destination) is greater than N (current position), so the expression will be 1 so far. Second is -(M<N), which will evaluate to -1 if M is less than N, so this subtracts 1 in this case. This can only be true if the first expression is false, so the expression will now equal 1 if M>N, -1 if M<N, or 0 is neither are true (M=N). This offset is then applied to N, either moving N in the appropriate direction towards M or, if N already equals M, not changing it at all.: min(max(K=1-(K=4)*8+M,28),52)→M>N-(M<N)+N→N: : .ADD RAIN: .Add a new rain sprite every 5 iterations of the menu loop: DS<(A,5): Pt-Change(rand^96,1,Pic2): End: : .DRAW LOGO AND MENU: .Shift sandstorm: Z+1→Z: Vertical +: conj({L6},{L1},708): sub(DM): DispGraph: conj({L1},{L6},708): : End: .<MENU HANDLER>: !If M-28: sub(ADV): End: !If M-36: sub(TM): End: !If M-44: sub(CL): End: !If M-52: End: 1→X: End: .If menu bit is 1: Else: .If HELP: !If M-36: Disp Str2: End: .If SCORES: !If M-44: Disp Str3: End: .If QUIT: !If M-52: Disp Str4: End: End:End: Return::.<SUBROUTINES>:.DRAW MENU:Lbl DM:.∙=bitwise and:.□=bitwise xor:.┼=bitwise or:: .DRAW LOGO AND SANDSTORM: .Loop through the logo, 2 bytes at a time: For(B,0,148): .Logo data - End state: Black logo image on white bg: .XOR 65535 - Inverts logo data - End state: White logo image on black bg: .AND Rain image - If either is white (0), output is white, so logo and rain remain white - End state: White logo image and white rain on black bg: .OR *Must wait for data in parentheses to be parsed* :: .Sandstorm garbage: .AND Logo data - This is the original, black on white logo.
