Here is an example of what Irgendwer is referring to. In the first picture, you can see the car is ahead of the tires. This is because the position of the car was updated, then the DLI kicks off before the tire position is updated to match the car.

In the second picture, there are missing interrupts (red circles) and it looks like some of the tires weren't drawn.

Hey Guyz,

I have another question: when exporting ASM code from Atari Interlace Studio, I can compile it with MADS and call from CC65 with a JSR.

I have created some background GFX in mode G11, with no raster, no DLI, really simple case.

However, after initialzing the G11 graphics, the sprites don't show up properly.

Would you mind having a quick look at the ASM and C code, and let me know what I am doing wrong?

Cheers!!!

Try using the hardware registers for PM color since you are using a GTIA mode.

POKE(704+i, PMColor[i]); // Set Player colors

should be

POKE(53266+i, PMColor[i]); // Set Player colors

The xex crashes due to the FPS output as the OS is disabled at this point

Awesome, that worked!!!!

Well spotted buddy!!

8bit-Dude · October 18, 2017

So, back with more questions!

I have integrated my sprites animation with a CIN background image as shown here:

I still have a couple of issues:

(1) I set the colour of P4 (tires) with: POKE(53273, PMColor[4]); // Set Player colors

However, the colour flickers based on P0-P3...

(2) I have an issue with this line of code in the asm file: mva #$fe portb

This functions is used by CIN to disable to ROM, or something like that, but the functions clock() and cgect() in cc65 stop working.
If I comment this line I can use clock() and cget(), but then the CIN gfx do not appear.

Could you guyz give me again some advice?? Thx a lot in advance!!!!

The multicolored tires is a sign that gprior (623)/ prior (53275) are not set. Enabling the 5th player (bit 4) is what allows you to set the missiles to a single color. I see in your code, you set 623. 623 is a shadow register for hardware register 53275. Shadow registers get copied to hardware registers by the OS routines during the vertical blank as I understand it. Additionally, the clock memlocs (18,19,20) are also managed by the OS routines so that should explain the clock not working. I think this explains what is going here, but whether you use the OS or write custom routines to meet your specific needs is up to you.

Hey Schlortt

I will try to figure out the tire issue based on your remarks.

The OS stuff is much more problematic for me. I do not want to disable it, but the CIN code I obtained from Atari Interlaced Studio seems to require setting the OS off.

By looking at the ASM code, could you tell me why CIN needs it, and if there is a way to avoid switching off the OS.

I have integrated my sprites animation with a CIN background image as shown here:

Only a general remark: If you like to have at least somewhat acceptance for your game in PAL-land do not use CIN or other interlaced background graphics.

They flicker like hell and it's a complete different story to interlaced PMGs as the area is much bigger.

The issue may not be apparent one most LCD monitors but it is there.

+Philsan · October 18, 2017

I agree. Please don't use interlaced modes.

+CharlieChaplin · October 18, 2017

How about mode 15 PAL blending ?!?

+Philsan · October 18, 2017

Aren't the cars too small to be seen with mode 15 pal blending?

popmilo · October 25, 2017

Aren't the cars too small to be seen with mode 15 pal blending?

Cars could stay PM gfx like now.

Don't know how would darker background gfx in 160x96 look like combined with sprites on top....

Flash now doesn't work with browsers.

But you can continue to use Player Editor offline with the files you can download here:

Yep common problem with 2011 posts - stuff has all dead links. I wish everyone would stick with stuff like the archive.org or some way to keep uploaded links alive for longer. Sourceforge even keeps old projects alive for decades. I can still find 15 year old Dot Net code I posted on sourceforge - still good.
