Summary	07822: turtles: Turtles has two color PROMS flipped due to a production error
Description	Turtles has two color PROMS, 5H and 5J flipped in MAME. Switching these two by renaming each to the other, fixes this issue and the mystery boxes display blue and the background displays as red. I am proposing that 5H is actually 5J and 5J is actually 5H. Based on the STERN Turtles flyer, the background should be red and mystery boxes blue. https://flyers.arcade-museum.com/flyers_video/stern/44000402.jpg All hardware examples I have found of Turtles PCB, including boards I own, all have red backgrounds with blue mystery boxes.
Steps To Reproduce	Load Turtles and note the color of the background (blue) and mystery boxes (red). Rename 5H and 5J to each other and load again to note that background is now red and mystery boxes are now blue.
Additional Information	Service Bulletin release by STERN. See Upload File October 28, 1981 Lieberman Music Company 9549 Penn Avenue South Minneapolis, MN 55431 ATTN: Service Manager RE: Turtles Color Due to a problem in production, you have received the new Turtles game with the Color Proms 5H, 5F, on the KT-4108-2 board reversed. These chips were incorrectly labeled so please disregard those labels. This causes the reds and blues on the screen to be reversed. To correct this problem, please switch these two chips. Sincerely, STERN ELECTRONICS

Maybe MAME should keep the flipped roms version, cause history was also written by this version. But a version with the proms correctly placed should be added IMO.
No.18270 Tafoid Administrator Dec 16, 2020, 22:48	As near as I can tell, this has been wrong for so long... It was correct in MAME 0.21 and changed in MAME 0.24 where it seemingly has been like that since. I have more research to do

All arcades would end up with the 'incorrect' looking version, the majority of players likely recognize that colour scheme as it was widespread. Stern admitted they'd made a mistake. Some arcades would take on board that advice and swap the ROMs. Players in those arcades would be exposed to the correct colours. It therefore existed in both forms, and based on what people have found, the 'fixed' version is far less common (as I doubt most operators cared) It's basically a 'revision' even if the only difference is the ROMs got swapped around.

I have only seen Blue on a couple flyers and MAME. This also is true about Turpin and 600. So Sega Turpin and Konami 600, I have only seen these with red backgrounds. Example:
