Beiträge von Snoopy im Thema „Accessing VIC-IV features from BASIC10 / C65 mode“

    It seems that these lines aren't needed on the MEGA65 (Nexys board) for showing your sprite effect?

    I think the control bits survive RUN/STOP+RESTORE, since the C65 doesn't know anything about sprite bitplane mode. So once you've run the program, the sprites will be in bitplane mode until the next hard reset (or the control bits are being reset manually...)

    It also works without line 90-110 even after a complete power off and power on again.

    It seems that the MEGA65 starts with activated VIC-IV? :gruebel

    The demo works perfect with the Xemu emulator:

    hm, not quite 100% perfect... ;) on the real machine, the sprites are in bitplane mode, i.e., each sprite sets its corresponding colour bit (sprite 0 = bit 0, sprite 1 = bit 1, and so on), so the effect is that the sprites are changing the colour of the colour bars in the background.

    I have tested your sprite demo on the Nexys board. Here it works as you described:

    A curious thing is, that it also works with line 90-110 being deleted (without init VIC-IV and no pokes).
