Of course all of the table is in memory but I suppose there are many objects managed by the blitter to handle the display priorities between the ball and some elements like the bumpers. Moreover without speaking of the problem of the physic of the ball, there is well animated score panel (yet better in pinball fantasies). So it is not probably so easy to keep the 50 fps and probably required a good coding skill at the time. |

upper score panel may not use EHB but only 8 or 16 colors.

The score panel is not EHB its changed by the copper, it's a simple display that isnt stressing the Amiga one bit, other than flippers and masking the ball when it gets obscured by parts of the table, the blitter really isnt doing a whole lot, there are not a lot of things it needs to blit. It's why it can be EHB, because technically, as in workload, the hardware is easily able to keep up. Even the ball physics cant be stressing the CPU out that much (though admittedly it's the most complex part of the game), the lowly CPU in the SNES was able to cope without problems in that area. Pinball Dreams is a perfect example of EHB being used to great effect because it isnt so demanding |

Generally speaking, even if it's not "Shadow of the Beast 3" or "Stardust", many of the Amiga's particularities have been well exploited in this game. So in the end for the Amiga it is indeed a textbook case of the use of the EHB mode.But it's still well done and probably not that trivial. Of course the Amiga can do more extraordinary as a global technical rendering (but rarely as a global result) |

EHB mode is special, it has no color registers, so even if you created a 'blitter static bitplane' all you would have is a 'shadow' on all the other bitplanes, based on the 'texture' of the sixth bitplane; basically a mask. Sure you can create interesting effects, but that's not what you want to do, which can only be done for <=5 bitplanes enabled. |

A 1 bit in the sixth biptlane lowers the RGB value in the color register (technically every 4bit of the components has a >>1). A 0 bit leaves the color unchanged. |
