The graphic itself is a standard Micropainter image, that is, 160x192, 2 bits per pixel. The last four bytes of the palette data aren't used, and all the colors, save COLUBK are set to $0E.

If someone has a better pic, then fold it in.

The rainbow looked kind of wrong to me, so I´ve changed your code a bit. In the main loop you now can set the rainbow to appear on on the Logo, the Text or the Background. Or all at once.

Just didn´t change the picture.

It's just the definition of all the system variables. You can use the .h file of any g2f picture (created when saved as asm).

btw, if you want to scroll the rainbow up, a simple change from dey to iny in DLI has to be done:

	.proc dli

	sty regy

	mva >fnt chbase
	sta wsync
	ldy $14
	ldx #85

suggestion- add velocity and have it reverse, going one way and then the other !

Changing direction in Thom´s code works with using SBC instead of ADC.

You can also have both directions at once. I´ve just made Subroutines "SD" (Scroll Down) and "SU" (Scroll Up). Looks like this:

not exactly velocity, but...

new DLI code for that:

	.proc dli

	mva >fnt chbase
	sta wsync
	lda $13

	mva #$e color1
	sta wsync

	lda rega
	rti
;-------
chg
	lda what
	cmp #$88	;dey?

	mva $13 store
	jmp furth
c_dey

store is additional .zpvar .byte

Just using different colors affects the direction of the rainbow.

I also made my version, since all the ones published here I find with details in the length, shape and font. I also publish the source code in MADS.

Nice logo shape. Perhaps scrolling is too fast (worst in NTSC machines).

+skr · April 24, 2021

Thank you all guys, I´ve learned so much (I´m a total noob, srsly).

I very much like @ascrnet´s way using text mode. Have to check out later, how to have two different scroll directions in one line with that.

The last thing I didn´t understand was the "compressed" graphics, but changing the DL to Antic Mode D did the trick, as it uses 2 scanlines. So this is my last video:

You make me feel like 12 years old again. Wanted to do exactly this stuff then, but no other Atarians around, no literature, no internet etc.

it's direct so it's super fast ?

thanks to all who have shared their source code, you learn a lot. i share my second improved version with the rainbow in DLI with VBI. is there a way to disable the VBI before exiting the program? ?

Simply include another VBI, that just jumps to xitvbv and set it as VBI before exit or better save original VBI and DL and reset them before exit.

Ok, last one by me...

ATARI would have added the registration mark back in the days, so I added it. Rainbow is taller here and you can exit to a warm reset.

Source code for all will be added to my github place in a few minutes. Link is in my signature.

Leaving the rainbow in DLI and VBI leaves it compatible for PAL and NTSC I learned.?
I also improved the blackout effect of the ATARI word and last but not least, thanks to all of you who made your own versions, we learn a lot from you.

Now my fourth version with the rainbow down and up.

This version (latest checked in Github) is not working with some programs. For example when adding an image (G2F) thereafter, it will not work all times, the image doesn't start.

Is there a way to restore the system to its default before exit the program? What to add here?:

exit
   jmp WARMSV

If in the G2F code is commented this line, it helps, but I'd like to have a full compatible Fuji Rainbow Logo program instead of to make hacks to other programs.

; lda:cmp:req $14		;wait 1 frame

It breaks out of the loop at $2C05:

2C03: A5 14             LDA RTCLOK+2
2C05: C5 14     L2C05   CMP RTCLOK+2
2C07: F0 FC             BEQ $2C05
2C09: 78                SEI

Note: not tested specifically with this small G2F code. Pasted here in order to know what commands are used with G2F.

First of all thanks for sharing the code on github ?, but it is strange your version of fuji. There is a game that has a very good one of course it doesn't use the whole screen.

Regards

This the one Atari UK provided to developers - used on several of the final games produced for the 8bit line...

It was the same data as the Xanth F/X Swan demo - https://demozoo.org/productions/98552/
