|Summary||08296: ridgerac: pink evening sky is incompletely drawn (corners still blue).|
In "Ridge Racer" in the ("intermediate"?) level where in the 2nd lap the sky grows pink, the pink layer is incompletely drawn, i.e. it looks like a big pink transparent rectangle drawn over the original cloudy blue sky with the corners still blue (like wearing small pink sunglasses with seeing the blue sky at the side).
I suspect that the pink is a huge transparent rectangular polygon that is too big to be handled properly by the Namco GPU emulation.
|Steps To Reproduce||
Select "intermediate"(?) level and play until the sky grows pink. Look at its corners.
Instead of driving full laps, you can also simply drive through the 1st tunnel, then drive wrongways back to before the tunnel entry and repeat that a few times.
|Additional Information||Hardware: IBM Thinkpad X61t with CPU Core2Duo 1.6GHz, 4GB RAM, Win10 version 1711. The machine has no 3D GPU and so uses software rendering mode.|

Do you mean this?
It would be cool if you could add youtube links, savestates or inp files to better document the bugs you create.
Thanks in advance.

It seems not present in the original hardware:

Two things against this report:
1) As MetaGgod mentioned, no accompanying snapshots, video, playback or save state to make verifying by other parties much much easier.
2) This game is already flagged for having imperfect graphics and as policy, unless there is a heavy regression, we don't want bug reports for it. The machine would not have a flag if it was considered 100% accurate. A report exception can happen if you have good documentation/video that describe the way it actually looks on original hardware/pcb. A personal memory is not a valid original reference.. we need something tangible.

It's this (from TODO in driver source):
"- ridgerac fogging isn't applied to the upper/side part of the sky (best seen when driving down a hill), it's fine in ridgera2,
czram contents is rather odd here and partly cleared (probably the cause?):
+ $0000-$0d7f - gradual increase from $00-$7c
+ $0d80-$0fff - $73, huh, why lower?
+ $1000-$19ff - $00, huh!? (it's specifically cleared, memsetting czram at boot does not fix the issue)
+ $1a00-$0dff - $77
+ $1e00-$1fff - $78

|Ok, if this bug/behaviour is already documented. I thought Namco System 22 emulation only suffers of intransparent shadows.|
