I'm trying an experiment to see if I can do line art on a 2600. I've gotten down timings and cycle counting. I've been able to clock properly to create asymmetrical playfields (Using a spreadsheet to calculate time slices), but player, missile, and ball placement is really confusing to me.
The idea is I'm trying to use player, ball, and missile graphics to draw vertical and diagonal lines, but unclear on how to clock them to the proper position. I've been able to clock the player to *around* the position I want by counting cycles and using a strobe, bit I'm looking for a pixel-perfect placement of P0, P1, M0, M1 and the ball. Now, I'm not looking for a routine, just what is the proper sequence of setting and strobing of the registers to get the objects where I need them for the next scan line. I'm counting cycles by hand using opcodes (more than just simple nop slides) and just need the sequence of events. The documentation I've found is confusing... especially for missile and ball. (I get that you move these objects relative to their last position, which is great as it will allow me to make diagonal lines.) but setting up that scan line is not going like I think it's supposed to.
Help will be... umm.. helpful
