Dreamcast Software Development Standards/Ver.1.00E

#### 16. Image and Animation Restrictions (Pokemon Animation Problem)

> Recommended: Animation functions such as rotation should not be done with the Dreamcast logo other than those performed by the Boot ROM.

> Sega encourages providing appropriate warning notes on the packaging, such as "This game should not be played in the dark."

> The following guidelines have been provided by NHK (Japan Broadcasting Co.).

1. The rate of blinking of an image or light generally should not exceed three times per second, in addition to the following points:

(1) Bright red colors must be handled especially carefully.

(2) Further to condition 1, if a faster blink rate is necessary it should not exceed five times per second, and in this case, the change in screen brightness should be no more than 20% and total blink time should be less than two seconds.

2. Rolling of high contrast screens or sudden screen changes of more than 20% brightness should generally be limited to no more than three times per second.

3. Avoid allowing a regular pattern (stripes, spirals, concentric circles, etc.) to occupy most of the screen.
