This should be fixed, but it doesn't look so easy... Oh. Right. Damn. The reason I didn't do that is because the X coordinates of the bombs are stored in fine-coarse format, where you write the high four bits to HMBL and use the low four in a DEY-BNE loop to position the ball. To make them able to destroy the shields, you'd need to change that to store the X coordinates in standard format, and either use a lookup table or the Hconvert routine to get the FC_X value for positioning it. If you can make that change, I'll figure out and do the bombs-destroy-shields routine. >>> BTW, don't ask for invisible invaders... I'd have too many things to change. >> >>The mere concept of even trying to make the kernel do that had me laughing >>for about five minutes :) > >Don't you here a voice saying "nothing is impossible"...? :-) About two minutes after I wrote that message I realized that simply setting COLUPF to zero would work perfectly, except that you couldn't see the bombs until they dropped below the last row of invaders. -- Stella list is Administered by krishna@xxxxxxxxxxxx <Glenn Saunders> Archives (includes files) at http://www.biglist.com/lists/stella/archives/ Unsub & more at http://www.biglist.com/lists/stella/stella.html +-shameless plugs-------------------------------------------------------+ | Stella documentary at http://www.primenet.com/~krishna | | Nick's VCS links via http://www.primenet.com/~nickb/atariprg.htm | | Write the best game, win framed autographs of famous Atari alumni!! | +-----------------------------------------------------------------------+
