Atari 2600
Switch banking 4k+4k

I declare some constants in the Bank 0.
I need to use them, even, in the Bank 1.
Is it possibile to declare them only once in the Bank 0?
Because if I declare again in the Bank 1, it is necessary to change their name.

Thanks

Thanks.

Thanks for the info.

Hi.
What does it mean at the begin of the code (atari 2600)

org $80
org $f000
or at the end
rorg $FFFA

thanks

Ok I have understood the problem. In previous code I used TXS / TSX.
Thanks for help me to understand.

Thanks for the reply. I'll try to understand all that you write me.
For now, I am watching Stella in debugger mode. Yes the SP address, uses address used for store other things.
Must I set the SP to $FF? The $FF memory address is not the default address for it?

Hi, I am programming on Atari 2600. There is a problem is driving me crazy.
When I use JSR instruction, the return addres is written in memory location assigned for other things and not in the SP.
This create bugs.
Is there some reason for this?
Thanks.
