Just today I tried changing the screen to NTSC mode, and it worked.. I was wondering if my RFU was broken, but your solution makes perfect sense - I haven't had time to try it yet, but it ties in with everything - and I forgot to check those coordinates in timutil.. Next thing. Just recently I tried to add another sprite to the program - the laser that the rotating ship the previous code was supposed to produce can fire. It's in ok, but when I tried to draw it, despite using the values from the GetTimInfo() as the texture coordinate, I get the wrong coordinates. If, however, I modify the texture u+v values it works. Now, I think this is the following thing: How exactly does GetTPage() work? Does it return a magic value calculated from the inputs? Or does it poke the inputs into a table somewhere in the GPU and return a value? (ie, is it safe to do: for t=1 to 5 sprite[x].tpage = GetTPage(x,y,z,a) and expect all the values will be the same, or should I copy the GetTPage value into a variable first?)
