Hello,
This four sprites, is the screen, but five is hint, else insert 16x16 vram emulation sprite :

16x16 is part on vram and move normal (no 8x8 scroll) but on assembler, make
all function and I/O on port 0x98, but not possibile

Where is too slow this test on 4 x 16x16 on screen 256x212!)

This screen 256x212 on 1 color is possibile to make this 16x16 (not sprite) and animation
e position ed not have limit nè hint this image!!

On Assembler is the solution to make example :
+ 4 sprites insert
+ 4 16x16 insert (vram)

+ screen 32x24 (screen 2)
+ 50 o 60Hz is possibile

on msx1 is possibile on msx2!

Ok.

P.S.: This is important information to get the soluction to set My All Game. Ad Speed
is possibil.

The games are use 16x16 (vram) :
- double dragon
- Jack the nipper
- Operation Wolf (wow this games!!)
- flintstones (big this not-sprite )
- terramex (wow this animation !!!!) This is not sprite!)
Okey?

Hello,

Did you try hardware sprite flicker. Copy sprite attribute table rotated.

- double dragon

using charset, write 1 byte in nametable = move 8x8 pixel

- terramex (wow this animation !!!!) This is not sprite!)

ZX Spectrum method. limited background graphics, all background color = black.

No. This new 4 x 16x16 is not sprite, but vram and move anim / posit is simily a real sprite.
But my Assembler is not easy to make this 'ghost' on vram part for five sprites.
Can't make this example where not successy (too slow and error) : (
See anthor example
Green Beret (Msx1 Konami) and see 4 sprites is found, but 5* is hint and black image is not
hint!
else this is great solution for msx1 for my games !!
I'm use Wbass2 and SJASM mode assembler !

"hint sprite", you mean "hidden sprite"

speed: do not use "vpoke" style, read multiple bytes vram->ram port 0x98.
you can maybe use BIOS for port 0x99 address setup.

;HL = RAM address, B = loop counter
read:
 ini   ;c=0x98
 jp nz,read

then do sofware sprites with AND / OR instructions in ram.
then ram->vram

;HL = RAM address, B = loop counter
write:
 outi   ;c=0x98
 jp nz,write

green beret software sprites: turning some bits = 0 to black background color (the entire screen needs black background color), doing an AND operation. for speed, store those AND MASK images 8 times in memory, 8 x-positions.

Copy attribute tables sprites ? I'm Done this for all five sprite but
one (five) is hint again : (

Insert you with assembleer to this text for example
view all sprites updtate five sprite !!!

But this is not insert on BASIC (use DEF USR o CMD o CALL ) and
user this "formul" to make the games.

Ok.

DanySoft are you using an automated tool from english translation?

Hopefully some of these sub-forums suits for you and you can surely get someone there to translate your words into proper english, so more people can 100% understand your words and help you better. :)

Sounds good, now rotate once again, then yet another sprite is hidden

rotate rotate rotate flicker. sprite table in RAM, no rotation in RAM, ringbuffer copy -> vram.

It looks worse than translator software His profile says Italy.

Maybe this stupid example will open up the idea behind:

10 DEFINT A-Z
20 DIM X(7),Y(7),C(7),S(7)
30 SCREEN 2
40 SPRITE$(0)=STRING$(8,255)
50 ON INTERVAL=30 GOSUB 120:INTERVAL ON
60 FOR I=0 TO 7:X(I)=I*32:Y(I)=I+50:C(I)=I+2:NEXT
70 FOR I=0 TO 7
80 PUT SPRITE (K+I)AND7,(X(I),Y(I)),C(I),S(I)
90 NEXT I
100 K$=INKEY$:IF K$="" THEN 100
110 END
120 IF NOTVDP(8)AND64 THEN RETURN
130 K=KXOR4:RETURN 70

Do this correctly on assembler and the speed will be so fast that you almost can't see the sprites change.

Sorry to write english, but are Italian.
Use Google translation is necessary.
