My favoritest tiny release :)
You can watch plasma movements and stare at 256 diferrent color patterns ;)

I wanted to have a vsync too but no space left, fortunatelly it doesn't get much much much insanely faster in newschool machines, so it showed quite ok at the compo.

Quite cool for such a tiny prod.

This 64b looks actually better than some bad 256b.

hehe nice, altho you could've done some xor-texture-plasma-like thingy with some optimizing ("mov [es:si],al","inc si" <- stosb if you put DI as your vscr, etc.)

umm.... I thought plasma was a different effect. This just looks like an oscillating sinusoid to me.

I've seen a lot worse stuff in 64b

Danke.

Coll stuff for 64 bytes, like the fact that it changes palette to add some extra variety.

Btw. anyone know the theory behind the Baze pseudo-sine-generator? It's damn compact atleast!

Only BB Image is the lack of escape, but that's explained here.

The program can be optimized by 2 bytes if you swap di and si. Then you can use stosb instead of mov [es:si],al inc si. Code:

Code:org 100h mov al,13h int 10h push word 09000h pop ds xor si,si mov di,395 Singen: mov [si],ch add cx,di mov ax,40 imul cx sub di,dx inc si jnz Singen push word 0A000h pop es xchg ax,dx aloop: xor di,di mov bl,200 yloop: mov cx,320 xloop: mov al,[bx] mov si,cx add al,[si] add si,dx add al,[si] and al,dh stosb loop xloop dec bl jnz yloop inc dx jmp aloop
A problem: For the original plasma64.asm, TASM produces a much larger code than 64b. Why?

Pretty.

Very good plasma!
You can save here 3 bytes if you change the second half with something like
Code: xchg ax, bx L: mov si, 320 mov ax, di xor dx, dx div si mov si, ax mov al, [si] mov si, dx add al, [si] add si, bx add al, [si] and al, bh stosb loop L inc bx jmp L

Damn, overlooked obvious shrink by another 2 bytes:
from
Code:add si, bx add al, [si]

to
Code:add al, [si+bx]
