If I use the CB command for the colour bars they are black and white. I gather that this is because it defaults to NTSC for the colour bars. However, on my TV at least, after displaying the colour bars the 'brick wall' display is smaller!! The bottom of the picture on the display is raised about a quarter to a third of the screen's height. The top of the display is flush with the top of the TV screen whereas before it was a little way down the screen (about 1.5 bricks as an estimate). The actual darker box for displaying information starts the same distance from the top of the display and ends the same distance from the bottom. In essence, the display is smaller and moved up on the screen! Yesterday I was playing about with a modified version of the check program from the sample directory. I made it so I could adjust the x, y of the screen whilst the sprites were still bouncing around. This was done by modifying (extern DISPENV)GsDISPENV.screen.x and ..screen.y. If I move the y pos to a negative value to make the screen go off the top of the display then I get the same sort of effect as described above! I.E. the sprites still bounce correctly at the bottom of the display (which has moved up) but they still bounce when they hit the top of the TV screen instead of going off the top to meet the virtual top that is moved up off the display! (I hope you understand all that!!!) After discovering that effect whilst playing about with GsDISPENV I think it is obvious that there is a bug with the colour bars that is setting the y pos to a negative value upon exiting. Sorry if that was 'long winded'! It's one of my habits :( JohnT ------------------------------------------ Send e-mail to johnt@nettech.demon.co.uk Visit my web site at www.coco.net.uk/johnt ------------------------------------------
