Sega Mega CD II
From SEGA Retro
The Mega-CD comes in many forms, but in all cases the hardware adds the capability of reading compact discs, technology which in the late 1980s and early 1990s, was becoming a more affordable storage option than the traditional video game ROM cartridge of previous console generations.
A traditional Mega-CD does not act as a stand-alone unit, and needs to be hooked up to a Mega Drive via the expansion port located on the right hand side of the console. Mega-CDs do, however, require their own AC adaptor, meaning that in order to play Mega-CD games, two sockets will be occupied by the upgraded console.
Though one would expect the Mega-CD to simply give the Mega Drive access to compact discs, it in fact adds extra processors, memory and audio features as well, all of which can only be utilised by CD software. The Mega-CD does not, however, solve the issue of graphics, which aside from the ability to scale and rotate sprites on the fly, remain identical to the standard Mega Drive system.
The Mega-CD also offers stereo sound RCA connectors. The Mega Drive on its own will output a monaural audio signal to the television, with stereo only being available through the headphone port located at the front of the console. An external connection from the Mega Drive to the Mega-CD will allow all games to play through the television in stereo.
The Mega-CD can be used in conjunction with a Sega 32X to run one of the six Sega Mega-CD 32X games. Alternatively it can be used to just play regular 5-inch or 3-inch audio CDs.
20 games are compatible with the Sega Mega CD II

The Justifier
Released: 29th of October 1993
The Justifier is a light-gun peripheral for the Mega Drive manufactured by Konami produced specifically for Lethal Enforcers. A version was also made for the Super NES.
The Justifiers are shaped like revolvers (and are modeled after the Colt Python revolver), but are brightly coloured due to early 90s fears that light guns could lead to gun crime. They are controversial peripherals for other reasons too - namely the fact that they are incompatible with some games reliant on the Menacer, as Konami wanted accurate light guns for the console ports of the game and felt that the existing first party light guns (the Menacer and Nintendo's Super Scope for the Super NES) were not adequate enough to replicate the arcade experience. This was not much of an issue in Japan, where the Menacer was never sold. Lethal Enforcers and its sequel are only compatible with The Justifiers, and thus all versions of the first game came packaged with the peripheral.
The Mega Drive supports a maximum of two Justifier guns at once - the standard blue one, which plugs into controller port 1, and a pink one, which plugs into the blue Justifier with a 6-pin RJ-11 phone cord). The pink Justifier was only sold directly by Konami via a mail order offer. The pink Justifer is compatible with both, the Mega Drive and Super NES models of the blue Justifier. Because of this, the packaging for the second Justifier does not feature branding for either platform.
Like the Menacer and most other light-guns of the era, The Justifier relies on scanlines produced by CRT televisions, making them incompatible with newer LCD, Plasma or LED monitors.
