The international flag of Buddhism and the Tibetan variant flipping back and forth.

I'm no Hellmood so when I couldn't make it below 64b I threw in some palette changes and other crap.

quick shot: 47 bytes with ESC support

Code:

org 100h
push 0xa000
pop es
mov al,0x13
int 0x10
X:mov ax,0xcccd
mul di
movzx ax,dl
imul ax,byte 6
cmp ah,5
jl F
movzx ax,dh
imul ax,byte 6
F: mov bl,ah
mov al,[byte bx+si+table]
stosb
in al,0x60
dec ax
jnz X
ret
table: db 32,44,40,15,42

there is space for improvement or a message
but not today ^^

Nice, also the first three lines from the left resemble Romanian flag

41 bytes:

Code:

...
mul di
cmp dl,256*5/6
jb F
mov dl,dh
F:
mov al,6
mul dl
mov bl,ah
...

it seems we summoned frag :O
beautiful optimization giving me further ideas

-> 39 bytes:

Code:

...
mul di
xchg dx,ax
cmp al,256*5/6
jc F
mov al,ah
F:
aam 43
mov bl,ah
...

so with removing ESC check and switching to int10 plotting it is 34b

maybe 32b possible after all?

32 bytes:

Code:

%define d -(0x13)
db 0x7f+d,44+d,4+d,15+d,42+d
Z:cwd
add al,-d
int 0x10
mov ax,0xcccd
mul cx
xchg dx,ax
cmp al,256*5/6
jc H
mov al,ah
H:
aam 43
mov bl,ah
mov al,[bx+si]
mov ah,0x0c
loop Z

verrry dirty, but works (at least in DosBox)

We are entering deep coder Zen territory here, mucho impressive frag & HellMood. I need to study some opcodes.

Now for extra credit, can you make the fields in the rightmost section the same size? :)

added on the 2020-09-10 11:57:04 by El Topo

Not exactly due to the heavy sizecoding but there can
be a tradeoff, try w from 40 to 43, 41 looks ok
(and still 32 bytes ;)

Code:

%define d -(0x13)
%define w 41
db 0x7f+d,44+d,4+d,15+d,42+d
Z:cwd
add al,-d
int 0x10
mov ax,0xcccd
mul cx
xchg dx,ax
cmp al,w*5
jc H
mov al,ah
H:
aam w
mov bl,ah
mov al,[bx+si]
mov ah,0x0c
loop Z
