Thanks. I know I'm a bit over the scanline count but 272 seems to be ok for my TV . I don't understand how waveclear would affect the number of scanlines, since the kernel is unaffected.. And I am ok with a jump at reset.
Could it be that the logic that is performed after the waveclear is taking too many cycles? I even edited the code to jump straight from the wavweclear logic to the next frame bypassing the normal logic .
Play is pretty simple just fire with joystick and shield with button , start with button.
The number of enemies is RAM E1 . The number of enemies killed is RAM E2. If you make RAM E2 equal RAM E1 and then hit Frame +1, the scanlines jump to 292 , Total CLKs changes drastically, next frame is 178. then back to 272. Hmmmmmmm
