Need help with DATlib - Empty C roms - Page 1

Hello
I am trying (again) to setup a working DATlib / NeoDev environment, and I face the same problem as the last time I tried: I can't get DATlib to build the C roms properly. I tried to compile the demo included with DATlib 0.3, everything works except the C roms. I have no problem displaying stuff on the fix, but no sprites. I used the included makefile.
Here is my full zipped NeoDev folder: https://transfernow.net/ddl/neodev00001
Thanks in advance for helping me figuring out what's wrong

Strange things. I copied the DATlib folder to src directory of my SDK, and everything compiles properly!

Thanks for your answer. I am sure the problem comes out of my total misunderstanding of makefiles, as even with the bare NeoDev kit withoutt DATlib I can't get any sprite to display, even with a program I know is good (the included sample "sprites").
As there is no .bat build program, I simply do "make" then "makeroms" then "make clean", only to find out that the C roms are totally empty.
Do you use the included makefile?

defalt45 (./3):Do you use the included makefile?

Yes. I am use. But C rom are generating by not makefile, but by BuildChar utility and stored inside out directory in the your program sources folder. Its name is char.bin.

I figured out the problem. It was caused because of MAME that requires a certain file size for the C roms

Phe-e-ee-eeew! OK, good luck with programming!

Si tu as des problèmes pour lancer tes roms avec Mame, utilises winkawaks+loader.
Il suffit d'éditer le fichier asr.dat pour ajouter un jeu à la liste.

To solve your problems with Mame, use winkawaks + loader.
Just edit the asr.dat file to add new rom to the list.

Merci de l'astuce
Par contre maintenant j'ai un nouveau problème, dès que j'affiche plusieurs sprites à l'écran, ça reset et Z80 error.
/----
Thanks for the tip
But now I have another problem, when I try to display multiple sprites at the same time, it resets then Z80 error.

I have 2 pictures in chardata.xml, one is named "nsmlogo1" and the other one "jet". So, to display them both, what I think I should do is this:

picture logoNsmPict;
picture jetPict;

pictureInit(&logoNsmPict, &nsmlogo1, 210, 17,16,40,FLIP_NONE);
palJobPut(17,nsmlogo1.palInfo->count,&nsmlogo1.palInfo->data);

pictureInit(&jetPict, &jet, 209, 18, 10,10,FLIP_NONE);
palJobPut(18,jet.palInfo->count,&jet.palInfo->data);

But when I do it it crashes. Anyone has a clue about this?

Give us a link to your sources, please. We'll try to figure it out.

Thanks a lot, here is the link: https://ufile.io/5q7uc

For some reason I successed to build the program again. Please attach the screenshot with your BuildChar/compiler crash message.

It compiles with no error but the emulator crashes when the program runs

- to the neogeo.xml file in your MAME.

Thank you, but the problem is not caused by this. I can execute the program as puzzledp in MAME. What happens is that the emulator resets when I display more than one picture/scroller/sprite at the same time

Why do you need this absolutely unnecessary and pointless nervado? Adding of the new original romset to the rombase is a much more simple and comfortable way to launch own program.

In your code at Title_mvs, every frame you init the same picture, you must init only one time in your loop function like :

// main loop //////////////////////////////////////////////////////////////////// void USER(void) { int demo_timer=600; int flash_timer=0; int P1_continue_timer=0; int P2_continue_timer=0; int P1_game_over_timer=0; int P2_game_over_timer=0; int P1_input_delay=0; int P2_input_delay=0; int AES_user_mode=0; int AES_P1_credits=0; int AES_P2_credits=0; int AES_P1_state=0; int AES_P2_state=0; LSPCmode=0x900; initGfx(); clearFixLayer(); clearSprites(1, 381); palJobPut(0,9,fixPalettes); pictureInit(&logoNsmPict, &nsmlogo1, 210, 17,16,40,FLIP_NONE); palJobPut(17,nsmlogo1.palInfo->count,&nsmlogo1.palInfo->data); pictureInit(&jetPict, &jet, 160, 18, 10,10,FLIP_NONE); palJobPut(18,jet.palInfo->count,&jet.palInfo->data); SCClose(); while(1) {
And pictureInit(&jetPict, &jet, 160, 18, 10,10,FLIP_NONE); takes more than a tile.
Jet -> 209 and logo->210. I think you need at least 2 sprites for jet so something like jet -> 208 and logo -> 210

Thanks for your answer. I noticed that it worked when initialized only 1 time, but if I do so the sprites will be always displayed, or here some sprites should be displayed only at certain times. For example I display picture nsmlogo as sprite 12,13... and jet as sprites 11 and 12, and then I should be able to clear everything and display another picture/scroller/... with sprite id 11,12,13... which I cannot do if I initialize everything at the beginning of the code.

You can position them off screen or use aSpriteHide found on page 68 of the docs. I do believe that I had to use aSpriteAnimate after aSpriteHide to get the sprite off screen.

Thank you all, it finally worked.

Then give us a new link to your project! As I know, the sources of this project contains a lot of useful things I can use in my project.

It's just an example to init sprite but you can do it inside your function :
