概 要製造エラーによりカラーROMが反転している。
詳 細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.

All hardware examples I have found of Turtles PCB, including boards I own, all have red backgrounds with blue mystery boxes.
再現手順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.

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
