16 Colours in Mode 2?
« on: 16:28, 14 September 18 »
Interview with Christophe Lajoux author of the game "Infernal House". In it he states 16 colours were used in Mode 2 screens. How is this possible?

Lots of carefully timed colour switching!  Basically what he explains in the next paragraph.

Thanks dthrone :D
not color cycling, color spliting. You change the indexed color during the refresh, each frame at the same position. This need a very precise code where everything is precisely timed.
use RASM, the best assembler ever made :p

I typed in a program from CPC-Infos which had all 26 colours in Mode 2 with each line having its own colour.
* Using the old Amstrad Languages :D   * with the Firmware :P
* I also like to problem solve code in BASIC :)   * And type-in Type-Ins! :D
