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.

Thousands of Mega Drive multi-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 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 [[Sega Retro:Todo/Multicarts|multi-cart project page]].
+
Simlilar to more traditional bootleg game cartridges, the majority of unlicensed multi-carts originate from the far east, from factories in and around Taiwan, Hong Kong or in more recent years, mainland China. Third-party distributors often design the packaging and are ultimately responsible for selling the product; the same ROM can therefore appear all over the world but in different guises.

 +
Many multi-carts make the documentation process easier by having product code numbers on display (which in turn often double up as the cartridge's "name"). From this we can deduce series based on letter, or similar identifiers. In most cases, it is not known what the letters symbolise.
  
===Documented===
 
Some multi-carts have been documented in more depth, usually because the ROM has been dumped or the cartridge is unique among its peers:

==="Groups"===
In more recent years, bootleggers have chosen to label their produce more intelligently, and so newer multi-carts are generally easier to group together:

===Most included games===
{{MulticartRelease

Without additional bank-switching routines, the maximum cartridge size allowed by the Mega Drive is 4MB, so games chosen for multi-carts (which themselves may not be using a 4MB ROM) need to be smaller than this value. Most earlier multi-carts therefore opted for games that were either 256kB or 512kB in size, and as marketable characters were preferred, there are clear patterns with the games usually featured.

"Super 5 in 1", a typical unlicensed Mega Drive multi-cart.

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 multi-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 task.

Simlilar to more traditional bootleg game cartridges, the majority of unlicensed multi-carts originate from the far east, from factories in and around Taiwan, Hong Kong or in more recent years, mainland China. Third-party distributors often design the packaging and are ultimately responsible for selling the product; the same ROM can therefore appear all over the world but in different guises.

Numbered series

A variant of "KE-804", clearly labled.

Many multi-carts make the documentation process easier by having product code numbers on display (which in turn often double up as the cartridge's "name"). From this we can deduce series based on letter, or similar identifiers. In most cases, it is not known what the letters symbolise.

"Groups"

Dozens of multi-carts use this generic design. We can assume they are all related.

Many multi-carts lack unique identifiers, and with no ROM dumps or contextual details, can only be judged on general appearance.

Sega Retro has chosen to refer to these cartridge sets as numbered "groups". This is a temporary measure until more information is found. If a number is missing, it means ths group has been identified.

Others

Multi-carts in South Korea

Several cartridges were created specifically for the South Korean market, often containing Sega Master System or ported MSX games, and menus in Korean.

Master System compilations

A small subset of multi-carts only contain Sega Master System games.

Unsorted

We currently know very little about this multi-cart other than "it exists".

If we can't group by product code, developer, or physical appearance, we can only group by capacity, i.e. how many games are included on each cartridge.

Incomplete

Main article: Sega Retro:Todo/Multicarts.

The Sega Retro multi-carts project page lists multi-carts whose existence hasn't been proven, or has yet to be documented.

Most included games

Without additional bank-switching routines, the maximum cartridge size allowed by the Mega Drive is 4MB, so games chosen for multi-carts (which themselves may not be using a 4MB ROM) need to be smaller than this value. Most earlier multi-carts therefore opted for games that were either 256kB or 512kB in size, and as marketable characters were preferred, there are clear patterns with the games usually featured.

The top 20 included games is as follows:
