The Simpsons (jtsimson): Incorrect scaling and background colors in intro #813

Closed BMF54123 closed 1 day ago

BMF54123 commented 1 week ago

The scaling on the logo in the intro is very wobbly and the letters jump around a lot compared to both the original PCB and MAME. Footage of an original PCB can be seen here:

You can also see that the "S" in "SONS" completely disappears for a frame or two right before it switches to the next scene:

Additionally, the background color seems to be much too dark; it should be the same shade of blue as the following scenes. This also affects the background of the Konami logo, which is white on a real PCB:

I assume the logo scaling issues are related to various other sprite scaling issues that have been reported in this and other Konami cores.
