Have you noticed the bricks in mode runner are missing lines until a reset? Have you looked at that?

paulb-nl commented 3 years ago

That was caused by the async ce_pix divider which was always dividing by 8 which is not correct for hires games. A reset would change the phase between the divider and the core's pixel clock so different pixels would be skipped everytime after a reset.

I have changed it to generate a ce_pix on the falling edge of the core's pixel clock so it is always synced at the correct cycle. Async dividers shouldn't be used.

Did you mean to close this? Thank you for explaining the fix. Exciting. That has been bothering me for a while.
