Worth noting, this just seems to be an issue with the scanline renderer, it appears correct on pixel accuracy mode.

Per invertego: there are some registers that are only implemented in the dot renderer that need to be implemented in the scanline renderer as well.

I could be mistaken because I don't have my notes in front of me, but a quick glance at the code indicates that the VDC HSR (horizontal sync) register is the main culprit here. The performance renderer doesn't model its side effects.

Seems fixed at v134

@Shideravan please test properly when closing issues: this is still an issue with the scanline renderer as it always has been.

Sorry, I wasn't aware (or I just forget) that changing the settings and resetting the game weren't enough to actually change their state.
Good catch!

I'm going to close this issue as we have permanently enabled the pixel accurate renderer for the PC-Engine in code. There is no way for a user to change this setting for this core and related subcomponents at this point (without reverting code and compiling themselves of course). The scanline renderer had proven to be too buggy and raised a number of issues fixed by the pixel accurate renderer so it is no longer available.
