I want to make an application that can load from disk and fill 32K of atari memory....The program can choose from disk which 32K block (multiple 32K blocks(files) are on disk) will be copied from diskdrive to atari memory. What will be the most easy way to do that ? Probably it's loading atari DOS, start your app, and then the app has disk acces ? But then, every time i compile my source(on pc, MADS) I have to put the executable on the dos disk, load dos from disk in emu, start app in dos....that is a bunch of work to test the program... Is there a more easy way to do that ? And..is it possible someone can give me a very clear sample program how to copy data from disk ? I really don't know anything about atari sio Thanks !!

hmm...could you explain that ?

really, I'm not treating it that bad at all The only thing it does is moving and animating - as said, I'm learning how to let stuff work on VBXE in the zip file is the source and atr to try. Little apps i made for the ease of inserting bmp's in my prog- bmp rgb extract - extract RGB values from a .bmp (file oo-rgb.txt) other is bmp raw extract - extacts all picture data from .bmp( no header/rgb etc) ( like file mario-raw.txt) screenshot mavbxe.zip

Wow, this looks truly above my espectations ! In comparision to MOOD from the c64 this looks far more detailed and colourful ! Great work ! Hope you stay motivated to expand it ! I saw this ZX movie : http://www.youtube.com/watch?v=vzm9KkJ5lGI&NR=1

That does the trick ! and thanks again for the very fast reply !!

question about blitter masks....: what do i need to set for blt_and_mask and for blt_xor_mask to get that the blitter gets displayer over the background, but that color 0 from the blitter will be transparant ? Thanks !

Right now at the moment there is not so much to show, because I'm busy studying and trying xdl's, bcb's etc.(and probably i'm not the best programmer around here ) But when i got some nice colourful moving graphics I will post it here ! or you mean the little rgb extract pc app ?

Thanks guys ! I've made a small app for pc that extracts the rgb.

Thanks for the quick repies ! hmmm... I'm using atari++ 1.55 9 bytes in the list. 10 bytes in the list. 9 bytes in the list. That brought the solution, GroovyBee ! coltab-g has 10 bytes and R/B has 9 bytes in the source! i did overlook that..after removing the last ,255 from G and adding ,255 to R and ,0 to G/B it works ! pffff Now I still have another question : When i make a 256 color bitmap, how can i extract the right r/g/b values and put them into my source ?

today i'm trying to find out how Heaven's bliiter1 example works, but i really don't know how the palette stuff works : ..... ..... ldx #0 stx VBXE_CSEL ;which colour # to change ldy #0 VBXE_SetPalette_l1 lda coltab_r,x sta VBXE_CR ;R lda coltab_g,x sta VBXE_CG ;G lda coltab_b,x sta VBXE_CB ;B inx cpx #10 bne VBXE_SetPalette_l1 rts coltab_r .byte 0,0,0,0,0,0,0,32,64 coltab_g .byte 0,32,144,64,176,96,208,255,255,255 coltab_b .byte 0,0,0,0,0,0,0,32,64 first thing is : ldx #0 stx VBXE_CSEL ;which colour # to change I assume that the rgb value of colour $00 will be changed, so that will r-g-b = 0-0-0 Is it true that with every new write to vbxe_cr/g/b register automaticly the number of vbxe_csel will be increased to set the next colour value ? so : colour $01 will hold r-g-b = 0-32-0 ? and colour $02 will hold 0-144-0 Then I added to the used bitmap (024.bmp) putting between the bytes (which are $00-$09- and after the header of the .bmp) some bytes holding some $0A 's to get an extra colour, and i added in the source at the data of coltab_r behind 64 the value 255 (and at coltab g/b a 0) so that bytes from the 024.bmp with $0A will get the r-g-b = 255-0-0 red colour... (and the cpx #10 changed to cpx #11) But that doesn't get me displayed some red color (the pixels(bytes) in the .bmp with $0A will be black onscreen... ) Probably i'm doing something stupid, and it's true this is the first time in my life I read something about palettes Thanks !!

Now the last little bugs are fixed Yars_strike.zip

Thanks for all the warm comments ! Thanks Fandal for finding those things ! *1 never used it before, but will it be important if the game will be loaded from a dos ? Is it enough to put in 2E0-2E1 $2000 where the game code starts ? *2 This was my first time ever doing some pokey sounds ..The only thing i do is sta $00 in AUDCTL to intialize it, what should i change to intialize it the right way ? Funny fact is, that by testing on the wiixl(atari800) emulator the sound screwed up, and with atari800win it seemed allright. I tested it also on real hardware (65XE) and it worked properly. Strange ! *3 as far as i can see, there are no ORG's in $C*** or code leaking in this area, probably i'm missing something.. As soon as i know how to put things right I will upload the fixed versionn

I Think our hero is named Yar (that's what he is called like in the 2600 manual) 100% 6502 The source code looks like crap

I programmed it from scratch...only ripped out the yar bit pictures from the original

Wow ! that will be great in colabration with the VBXE board ! Are there already some sound samples the atari has produced with the prototype board for us to hear ? very cool !!!

pictures :

For this years 4K minigame compo I made a little game : Yar's strike. It's a remake from the classic Yar's revenge from the atari 2600. It features 8 levels before yar is finally safe home.... After 6 year's non 6502 programming it was real fun programming this every now and then last two months ! The primay objective is to break a path through the shield and destroy Qotile with a blast from the Zorlon cannon. The secondary objective is to score as many points as possible ! For more information, and how to play see the readme file in the .zip file. Boot with basic disabled. Have fun ! Let me know what you think of it ! Thelen Yars_strike.zip

WOW ! that's a major task........ the boards are getting shape already ! your work is indeed very much appreciated !

:thumbsup: very good demo ! I never exspected he would ever die....It was a real shock to me.

well, i have a spectre too from the flea market but i never tried it... What i would like to see is some information from waht macintosh computers the roms can be removed and inserted in the spectre GCR. And i think it would be nice to see some in action screenshots. Thanks for the great site with information !

ah, what a funny game ! luckely it has been saved from the moldy basement ! I did about 15 minutes over level 1 - it looks like jumping into traps is my favorite good work !

Very cool and adictive game, I enjoyed playing it ! althoug i'm not always quick enough looks very difficult to me to fit everything in 1K :thumbsup:

Wow ! really cool to see the boards ! Are you going to do all boards by hand ? meaning putting all the solder paste , placing the components and bake it on a hot plate ? At my last job i did a lot of prototyping including 0402 SMD....pffff

I think you're doing very well ! looks great !!

That's very good news ! please keep us informed
