i've got this semi-working in my fork, but the turret placement isn't quite working out right, i guess i have no choice but to redraw some sprites, but i've got a draw routine in place for it. i'm gonna try to work on the sprites for it today, get it looking just right, thankfully, because of the way it is drawn, the turret can appear "embedded" in the chassis rather than superimposed. i'll let you know what level of success i can achieve, this idea is well worth the effort.
