Summary	03644: tmnt2, ssriders, suratk: Graphic error with high priority shadows
Description	- In TMNT stage 4 "Prehistoric Turtlesauras" when it enters the cave, some rays of light illuminate the characters in the original pcb and not in the emulator. - In ssriders at the dance demo scene with spot lights, some lighting effects are not applied properly. - In suratk, sprites behind the glass wall in level 3 (also seen in attract mode) should be dark
Steps To Reproduce
Additional Information	This error I have also seen in "Metamorphic Force" also checked with the original pcb.

No.05401 abelardator2 Tester Jan 5, 2010, 15:23	Yes, taking pictures of the original pcb, please wait.

No.06079 hap Developer May 10, 2010, 22:56	sorry, I've reverted my fix due to it being too intrusive with the possibility it breaks priorites in other games
No.06099 abelardator2 Tester May 12, 2010, 13:30	Thanks for putting interest in repairing konami games. I will continue to report bugs with my collection of original PCB games.
No.06143 Fujix Administrator May 19, 2010, 16:38	Merged with 03853 (the lighting effect issues for ssrides) reported by abelardator2.
No.06147 Haze Senior Tester May 19, 2010, 23:54	it might be worth simply creating a private implementation if you're uncertain it should be in the core. While it might seem 'ugly' it's entirely possible that the behavior on Konami boards is unique, different manufacturers had different design ideas, and the generic code doesn't always suit them.

No.06191 Sune_S Senior Tester May 28, 2010, 03:08	I can't tell what's wrong with supratk from the screenshot? The baddie is supposed to be behind the glass.
No.06193 abelardator2 Tester May 28, 2010, 08:49	Sune_S, I suppose that the enemy should have a darker tone, due to the effect of crystal.
No.06195 hap Developer May 28, 2010, 15:30	yes, you missed the bug description above: "In suratk, sprites behind the glass wall in level 3 (also seen in attract mode) should be dark "
No.06198 Sune_S Senior Tester May 29, 2010, 02:17	Damn, yes I missed that, sorry.
No.22310 abelardator2 Tester Sep 8, 2024, 10:17	I added a new comparison of the problem in SunsetRiders.
No.22313 Augusto Tester Sep 10, 2024, 00:07	That bug is protection or graphics code ?
