The Sega CD shelf is lit up and ready — every game here boots straight in your browser, no downloads, no dust. Sega hardware from 1992, running for real.
The Sega CD plays CD-based games and adds hardware functionality such as a faster CPU and a custom graphics chip for enhanced sprite scaling and rotation. The Sega CD, known as Mega-CD in most regions outside North America and Brazil, is a CD-ROM peripheral and format for the Sega Genesis produced by Sega as part of the fourth generation of video game consoles.
They didn't want to send us working Sega CD units. The American staff were frustrated by the Sega CD's construction. We worked around the clock, trying to catch the failure in-progress, and after about a week we finally realized what was happening." He said the problems were caused by certain games excessively seeking to different tracks on the disc (as opposed to continuously playing / streaming), leading to overheating of the motors which repositioned the laser head assembly.
In addition to relatively short loading times, Takami's team planned to implement hardware scaling and rotation similar to that of Sega's arcade games, which required a dedicated digital signal processor. However, two major changes were made towards the end of development that dramatically raised the price of the add-on. Responding to rumors that NEC planned a memory upgrade to bring the TurboGrafx-CD RAM from 0.5 Mbit to between 2 and 4 Mbit, Sega increased the Sega CD's available RAM from 1 to 6.5 Mbit.
According to Bayless, "It was a fundamental paradigm shift with almost no thought given to consequences. The whole company fell in love with the idea without ever really asking how it would affect the games you made." Sega of America producer Michael Latham said he "loved" the Sega CD, and that it had been damaged by an abundance of "Hollywood interactive film games" instead of using it to make "just plain great video games". Each device requires its own power supply.]] Near the time of its release, the Sega CD was awarded Best New Peripheral of 1992 by Electronic Gaming Monthly.
GamePro cited the same problems, noting that many games were simple ports of cartridge games with minimal enhancements; GamePro concluded that the Sega CD was merely "a big memory device with CD sound" rather than a meaningful upgrade. Retrospective reception of the Sega CD has been mixed, praising certain games but criticizing its value for money and limited upgrades over Genesis. Jeremy Parish of USgamer wrote that Sega was not the only company of the period to "muddy its waters" with a CD add-on, and highlighted some "gems" for the system, but that "the benefits offered by the Sega CD had to be balanced against the fact that the add-on more than doubled the price (and complexity) of the [Genesis]." In a separate article for 1Up.com, Parish praised the Sega CD's expansion of value to the Genesis.
