DEBRO Posted August 18, 2003 Share Posted August 18, 2003 In the development documents there is mention of a "Kangaroo" mode. What is this? I've looked at Kangaroo but don't quite understand what they mean. Am I missing something? Quote Link to comment Share on other sites More sharing options...
jindroush Posted August 18, 2003 Share Posted August 18, 2003 It just makes black non-transparent (if I recall that correctly). I also don't understand what it has to do with Kangaroo game Quote Link to comment Share on other sites More sharing options...
EricBall Posted August 19, 2003 Share Posted August 19, 2003 (From the 7800 Software Guide:) Bit 2 ($04) of CTRL enables "Kangaroo" mode which eliminates transparency, so that any pixel of color "0" will be background color, rather than transparent. Most games will leave this off since it would result in rectangular sprites. However, the 7800 Software Guide also mentions Kangaroo mode in relation to the 320 modes. The 320 modes have a quirk where transparency only works if the even/odd pair of 320 pixels are both color "0". Otherwise any pixel of color "0" will be background color, rather than transparent. Note: Kangaroo and the 320 quirk is not yet implemented correctly in MESS. I have an update to the driver, but I haven't submitted it yet. 1 Quote Link to comment Share on other sites More sharing options...
