cc65 inverse characters

[kensu]

Does anyone know how to display inverse characters when using cc65? The only method I've come across involve either using Print #6 (which even if it has an analog in cc65 is useless, since I'm loading the characters directly into screen memory using memcpy). How is this handled in assembler?

Turn on bit 7 I think. And it only applies to gr. 0 style characters.

ATASCII > 127 makes inverse chars.

 

For Graphics 0 it inverses the characters. For Antic 4/5 it replaces PF2 (bit pair 11) with PF3. And for Antic 6/7 (Graphics 1) it enables the high ranges (PF2-PF3) of characters.

You could try something like that:

 

#define INV((a)) ((a)|128)

 

...

 

char inverseString[] ={ INV('H'),INV('e'),INV('l'),INV('l'),INV('o'),INV('!'),0};

 

...
