if you want boot & load to $0800-$bfff use this:.
copy your game to disk, rename game to xbios.com and boot
if you want direct load to:
$0000-$00ff, $0200-$06ff, $0c00-$cfff, $d800-$ffff use xbios (xbios use ataridos fs/mydos up to 16mb, catalogs, custom SIO)
Awesome, just what I needed!!!

Hardly to be done depending on the code...
Why not using RMT track? There you can export to desired adress.
Yeah, that's what I have for now.
But I am writing a kind of Game Dev Kit for cc65 (c64/a8), and SAP support would make things easier in many respects.
-
Thanks Xuel!
By the way, to you know a way to relocate SAP files?
I would like to have the entire code located at 0xF000.
-
Hey Xuel,
Would you mind working your magic on the attached SAP file?
I can find the load addresses, but no idea where to find the init and frame addresses...
Thx 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.

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 xex crashes due to the FPS output as the OS is disabled at this point
Well spotted buddy!!
-
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
Awesome, that worked!!!!

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!!!

Shlortt, Irgend,
I have implemented a sorting algorithm that allows me to set DLIs in the right order, as I fill the sprites memory for the tires.
When refreshing, I move all the sprites to hpos zero, then clear the memory and reset the DLIs.
Some extras include flicekring between two players when they line up horizontally.
The animation is 99% correct, I am very very close, but there is a residual "jumping" of sprites that I cannot get rid of.
Could you please check the attached video/xex, and have another look through my sources to see if you spot something strange?
I would really deeply appreciate it!

Yes, it uses Winpcap. I've avoided using this driver because it has multiple problems: poor security (all programs can use it once it has loaded), licensing issues, and it is detected as potentially unwanted software by some antiviruses. At the time, there was also a problem with SoftEther VPN installing a Winpcap lookalike driver that has the packet sending API subtly broken. There is a new driver called Npcap that shows some promise but I haven't tried it yet.
Thanks for the clarification. Hope something may be worked out in future with Npcap!

Alright guyz, I am almost there!!!
Now my tires follow each car nicely, and I only get a bit of flicker due to the fact that the background is a character based screen (8 rows per DLI).
I would like to start using Graphic Mode 15, to refine the DLI, but there is precious little information on how it works in CC65.
I tried writing _graphics(15); and the screen just went black (PMG also completely disappeared).
Would you have some tips and advice to help me get setup?

Altirra's NAT does not support ICMP. You'll need to use tunneling to a gateway supporting the VXLAN protocol to use pings from within the emulation.
Thanks for the quick answer buddy!
By the way, WinVICE support ICMP, it is very helpful for networked games (to know the latency).
I am developping a cross-platform (C64/A8/AppleII) top-down racing game.

Good idea about using VBI for setting first position.
I have added a sorting algorithm which fixes most of the out-of-sync.
There are still some flickers though... mind having again a look?

DLI: pha ; save registers ldy DLIIndex lda _DLIData,y sta $D003 ; set hpos of PM3 iny sty DLIIndex pla ; restore registers rtiHad only a very quick look (5 sec.). I think TYA PHA ... PLA TAY is missing at least...
Amazing, that was exactly the issue.
The memory corruption has been fixed.
There is still a problem with the code though, see attached xex and sources.

Version 2.90 of my emulator Altirra is now officially released:
And, now, time to start the next set of test releases:

Hey Phaeron,
Thanks so much for your continued development of Altirra, amazing work!
I am using Altirra to develop an online game, and ran over a strange issue while using IP65.
Most demos (including GETURL) work perfectly fine.
But the PING example (see attached xex) returns an error code 82 in Altirra (2.8.1 and 2.9.0)
I tested on my actual 130XE with DragonCart, and the program runs just fine.
Could you kindly investigate the root cause of this problem?
Thanks in advance!

Hey guyz,
So I have written a VBI / DLI combo to shift the HPOS at various scanline.
My code is *almost* working, in that I can show the tires 4 times, and shift them with the DLI routine.
However, something is not right in my routine DLI:, it corrupts memory and crashes the prog after few seconds...
Would you mind taking a quick look:

I think that I can do something pretty efficient with DLI... working on it now.

So Irgend, I am back with some progress.
I decided to use P0 to P3 for the vehicle body, and flicker P4 (Missiles) for the tires.
My first version flickers the tires one vehicle at-a-time, between 4 vehicles, so it looks very shaky (see attached xex and video).
For my second version, I would like to setup a list of scanlines for which I change the P4 horizontal pos.
This way I can show the tires as many times as possible within one frame (i.e: whenever two vehicles do not line up horizontally).
Would it be possible to share with me a couple of ASM codelines showing how I can trigger code for specific scanlines?
P.S: my current code is shown below:

Thanks for the further help Irgend!
I am talking with Popmilo and Schlortt in order to figure out the best strategy for displaying the Map and PMs with best colours possible.
I should perhaps start a new thread....
-
Irgend,
Thanks for providing the example, it looks like what I imagined.
In most cases my sprites will not line up horizontally, however, they will sometime do (I am programming a top-down racing game).
For instance, on a straight horizontal piece of track, the 4 sprites may all line up horizontally.
So I guess I am left only with using the missiles, perhaps by mixing colors (P0/M1, P1/M2, P2/M3, P3/M0)... But that is too bad, because my sprites ideally need to share 2 colors (black for tires, cyan for cockpit) as shown in the attachements below.
Cheers,
Tony

I'm glad to help, but you gotta tell me what MGM is
There's no obstacle for PM and what ever gfx mode that is to work together I guess.
Thanks Popmilo, I have just sent you a PM now.

Irgend, for the game I am developping I need to show a multicolor map in 160x192 (JAG ok), with 4 Players on top.
However, JAG seems to hack into the PM code to cover-up the left/right sides of the screen, which means they are not available for player drawing.
Is there any way round this?
