Has anyone tried to code for the Atari 2600 in C wirh CC65? I am trying to figure pout how to code the display. I understand I need to control the raster. I am looking for a simple "Hello World" example.

Hi Is it possible to use CC65 to build rom images for the Atari 7800? How? It seems to me that the console is not supported out of the box by CC65. Fabrizio

Hi everyone, I would like to add redefined characters to my multi-system 8-bit game CROSS CHASE https://github.com/Fabrizio-Caruso/CROSS-CHASE/releases It currently looks like this: For the ATARI XL target I would like to have both mode 1 and redefined characters. I supposed that I need to do something with the cryptic .cfg file to reserve some RAM for the characters. What do I need to do exactly? Could someone show me an example? -
Hi! My little multi-system 8-bit game supports the Atari computers (in both mode 0 and 1) and Atari 5200 console (in mode 1). https://github.com/Fabrizio-Caruso/CROSS-CHASE/releases How can I use the fifth color in mode 1 and do this with CC65? My game always shows only 4 colors. No matter which character code I select. I must be dowing something wrong.

I am trying to write an ATARI 5200 version of my cross-system 8 bit game: https://github.com/Fabrizio-Caruso/ASCII-CHASE (which already supports most 8 bit Z80 and 6502-based computers) I have managed to compile my code with CC65 for the Atari 5200 target by using conio. (I was wrongly using keyboard input on a keyboardless console...). My problem now is: - how to use the binary created by CC65? Can I use it as it is? Which extension should I use? Should I use it as a cartridge? - how to set up the emulator? Which rom? Atari800Win with the 5200 rom goes straight to the debugger when started.

Hi eveyone, I am using CC65 to code a game that use conio.h to display characters on the screen. It works fine in graphics mode 0 but I get weird results with other text modes. (I am compiling with cl65.exe -O -t atarixl --start-addr 0x4000 ... to get enough memory). I would like to use any other text mode that adds support for colors like graphics mode 12. (I would use re-defined characters but this is not my issue). My goal is to have a text mode with at least 4 colors and to know how to draw characters and set their colors with CC65. (1) If I set graphics mode 12 I get the lower four lines in monochromatic mode. Is it normal? I thought it was a BASIC thing. How can I get read of them? (2) The conio library seems not to behave correctly when used with any graphics mode other than 0. How to I set colors? Where can I find any simple example? Fabrizio

Hello everybody, am trying to figure out the best way to do SDX system calls from C via cc65? For example, there is a routine that can be called to get the current date and time: void timedate(TimeDate* td) { struct regs r; assert(td!=NULL); r.pc = 0x703; // KERNEL r.y = 100; // GETTD *(byte*) 0x0761 = 0x10; // DEVICE _sys(&r); // Do Kernel Call. td->day = *(byte*) 0x77B; td->month = *(byte*) 0x77C; td->year = *(byte*) 0x77D; td->hours = *(byte*) 0x77E; td->minutes = *(byte*) 0x77F; td->seconds = *(byte*) 0x780; return; } Is it possible to use a similar mechanism to get access to the other SpartaDOS X functions? For example, I need to be able to set errno, when one module of my program goes byebye, so that I can call the next program module to load (and to cut down on footprint. I do not want to write a whole overlay system when I can use the OS to do it reliably). What I _want_ to do is have an overreaching TSR program (which I'd LIKE to be able to write in C), which will provide serial routines that I can call (open, close, read, write) from the other system modules (LOGIN.COM, BULLETIN, MSGBOARD, FILBOARD, BYE, etc.) and thus not only keep the memory footprint down, but to maximize modularity/flexibility. -Thom
