Thanks a lot Wrathchild! It really helped me.

Maybe I misunderstood the question, but "lda 10" - this instruction do load value 10 into accumulator.

cc65 V2.16 - Ubuntu Yes, I get also gray color, but shouldn't the color be brown? For experiment, in this case I got brown border color. I think this problem in the format number representation hex/dec. .importzp sp .import incsp1 .export _foo .segment "CODE" .proc _foo: near .segment "CODE" lda 10 sta $02C8 rts .endproc

Thanks again baktra! I tried call asm proc as you recommended as fastcall. But anyway I got wrong value in asm. I don't not what happened, why this code don't working correctly. #include <stdio.h> #include <stdlib.h> #include <stdint.h> void fastcall foo(uint8_t c); int main() { foo(10); while(1){} return 0; } .importzp sp .import incsp1 .export _foo .segment "CODE" .proc _foo: near .segment "CODE" sta $02C8 rts .endproc

Thanks you guys! This is my mistake, RST instruction really need. I fixed my assembler code as baktra said. But problem not solved, the FOO function not get right value from stack. How can I do debugging the code at execution?

Hi everyone! I started programming A8 in the C (CC65). My idea is doing main programming in C and call assembler subprograms. It's work fine, but I don' t know how I can make a call the assembler procedure with arguments. For test, I wrote small code for change border color. I can't understand why it doesn't works, pls help me.. /* / main.c */ #include <stdio.h> #include <stdlib.h> #include <stdint.h> extern void foo(uint8_t c); int main() { foo(10); while(1){} return 0; } ; ; foo.s ; .importzp sp, sreg, regsave .export _foo .segment "CODE" .proc _foo: near ; get arguments ldy #$00 lda (sp),y ; set border color sta 712 .endproc For building cl65 -t atari main.c foo.s -o app

Thanks! I can do sort games at www.atarimania.com or other site by screen resolution?

Thank you Chris Yes, please send me this files, if possible in the .st file format.

About mono compatible of games I don't know, but also no any audio from games. Mega ST2 can detect connected monitor?

Hello everyone, I have problem with load games on the Atari MEGA ST2 with monitor SM124. After run game from floppy I get GEM interface without any errors or just a black screen. Diskettes with games tested. Mega ST2 compatible with 520/1040 ST? May be problem with RAM/ROM, how do check it? Any ideas...

Thanks guys! Quadrunner Interesting info about ATR format. If be a free time I will think how to convert ATR to synth RAW. River Patroller Yes course I have Atari 1050 and Indus GT real drives. I don't know what density in my ATR. Kyle22 SIO2PC - that's what I need now! Where I can download Atari disk images for write by Kryoflux?

Hello everyone! I have Kryoflux device and Atari disk images in ATR format. But I don't found information how to write ATR images to 5.25" disk. Pls help me make do it... BR

Thank Thomas! I love Riga too. I was in Munich, it's very nice city and tasty beer

PM sent for Indus GT drive. Thanks!

Привет, взаимно! По каким компам/играм фанатеешь?

мое почтение! мало ни мало, но чутка есть, а точнее нас уже двое

Yes, if video connector don't swing, Atari never boot. I think about detection of this problem

So, I found two problems. * Blue screen - broken SCART cable, no signal for red color ** Atari still boot, if swing a video connector (up/down)ю Maybe micro crack on PCB (I do not know how to check it...) About capacitors on PSU, they need to be replaced

Thank, tonight will be what to do...

OK, I will check PSU For test I can use ATX PSU from PC? There is also + 5V & + 12V

Thanks Moonsweeper, good job! But blue screen can be if PSU is corrupted?

I use LCD TV, no, if no a signal (Atari is off) just is black screen.

Nothing is happening, just a blue screen.

Hello everybody! I'm novice and bought on Ebay Atari 1040STF. Computer successfully earned, but after 2 hours of fun has stopped working. After power up I see the 'blue screen' (photo attached) and floppy drive is silent, keyboard does not react. I checked power supply, voltage +5 and +12 is ok. I'm shocked and don't know what the problem((( Please give me instructions for how to diagnose the problem. p.s. sorry for my english
