How to set up CC65 for redefined chars and mode 1 for ATARIXL?

[Fabrizio Caruso]

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?

The easiest way to reserve memory at "aligned address" is by moving higher the STARTADDRESS in cfg file e.g. to $3000. Then you can freely use memory between $2000 and $3000.

Take a look at these examples:

In the long term, you would have no choice but to master those cryptic .cfg files.

I would recommend the http://atariage.com/forums/topic/259931-atari-8-bit-games-in-c-cc65/ thread for more information and example games with full source code available.
