Mega Drive unlicensed multi-carts
From Sega Retro
A common practice amongst video game bootleggers is to combine two or more games into one - in the Sega Mega Drive's case, resulting in unlicensed multi-carts. Such an idea is particularly prominent in Asia and South America - often moreso than the act of releasing bootlegs of individual games.
The process is achieved by using high capacity ROM cartridges - with early games such as Tetris shipping on 256kB ROMs, multiple copies can be placed within a 2MB or 4MB ROM with room to spare. Sometimes a simple menu would be programmed to select between the titles, or a soft reset of the console is required to switch games.
Unlike the Nintendo Famicom, in which multi-cart sizes ballooned during the 1990s and 2000s (to the point where manufacturers would (often erroneously) claim a multi-cart contained hundreds of games), it is more common to see Mega Drive multi-carts contain between two and eight games - typically when a cartridge claims to have more than ten, it is a strong indication that games will be repeated, sometimes with very minor changes. Newer Mega Drive games are rarely seen in multi-carts, not only because of their size, but due to tighter security from developers.
Sega have released multiple officially licensed compilations, which save for an expected layer of polish, offer much the same thing.

Documentation
Thousands of Mega Drive mulit-carts exist, with new ones continuing to be created today. While Sega Retro is attempting to document as many of these cartridges as possible, the volume of releases and the desire for their creators to hide their identities makes this an extremely difficult, if not impossible task.
Our documentation of unlicensed multi-carts is at a very preliminary stage, and as such we are only able to reliably group multi-carts based on appearance (with the view that a similar aesthetic likely means they are related in some way). Most multi-carts lack any sort of obvious pattern, making it dificult to cleanly represent them on this wiki. For an unorganised collection of other known multi-carts, see the multi-cart project page.
Known series
In more recent years, bootleggers have chosen to label their produce more intelligently, and so newer multi-carts are generally easier to group together:
- Mega Drive unlicensed multi-carts (DT series)
- Mega Drive unlicensed multi-carts (KC series)
- Mega Drive unlicensed multi-carts (KE series)
- Mega Drive unlicensed multi-carts (KH series)
- Mega Drive unlicensed multi-carts (KW series)
- Mega Drive unlicensed multi-carts (TH series)
Due to the sheer volume of releases, special consideration has been made for some countries:
