* Because the image data before playback is compressed to about 1/50 and the audio data is compressed to about 1/10, it can be recorded on a CD for 74 minutes. In addition, since playback is performed using a dedicated LSI, the CPU is not burdened at all, and you can play games while playing high-quality video.
MPEG / Video function: Saturn's MPEG / Video has various special functions customized for Saturn.
