Double Switch is strikingly similar to the Night Trap in a number of ways, most notably its use of a camera and trap system. Where Double Switch really stood out though, was its use of a far better known cast, many of whom you may recognize from movies and even music.
During this brief episode, I compare / contrast the Sega CD version against the superior Saturn version, and wanted to give you a good idea of how the performance was on either platform. Enjoy!

Sega CD + 32X
The cd 32x games use the sega cd cpu like all other cd based games. The 32x was there for the colors. The 32x and SegaCD are independent units, and both units, or neither unit, can be utilized by any game on the system.
The SegaCD supported an operation mode where the system was booted from cartridge rather than CD, and the SegaCD hardware was fully available in this mode. Flux is an example of a commercially released Genesis cartridge that used the SegaCD hardware. It would also be possible to create a 32x cartridge that uses the SegaCD hardware as well as the 32x hardware, although none were ever commercially released.
The main CPU is a 12.5-MHz 16-bit Motorola 68000 processor. The Mega Drive/Genesis has the same processor, but at a lower clock rate of 7.67 MHz (NTSC) / 7.61 MHz (PAL).
- Number of simultaneous colors on screen: 64 out of 512 (same as the Genesis)
- Display resolution: 320 x 224 pixels and 256 x 224, video size from ¼ to full screen
- Main RAM: 6 Mbit
- PCM samples: 512 kbit
- CD-ROM data cache: 128 kbit
- 500 MB CD-ROM discs (equivalent to 62 minutes of audio data)
- ¼ screen B/W footage video: 1.5 to 4 hours
- ¼ screen color footage: 45 minutes
- CD-ROM drive transfer rate: 150 kB/s (1x)
Understanding disc read speeds
For comparison, the 1X DVD rate is 1.321 MB/s, which is the data rate required to store 60 minutes of video on a 4.7 GB DVD disc, or about nine times faster than a 1X CD-ROM drive. For example, a 16X Max DVD drive transfers data as fast as about 21 MB/s, nearly three times the rate of a 52X CD drive.
What's the difference?
- Mbps means megabits per second. Mb is used for download and upload speed.
- MBps stands for megabytes per second. MB is used for file size.
