Multicarts are usually a single game cartridge that has more than one game on it. Since they are very easy to make, a lot of them are made by various pirate companies. They are most commonly found for the NES/Famicom, but they have been produced for many popular cartridge-based consoles, including the Atari 2600, Game Boy, Game Boy Advance, Mega Drive/Genesis, and Nintendo DS, among others.
- A whole bunch of pictures crammed onto the cartridge's art. Sometimes the pictures are from a more recent game (or possibly an unrelated film), or the official art has been edited.
- Misspellings of the game names on the cartridge and/or menu.
- A list on the cart (usually on the back of the box if it's a large number of games) listing the game names in English and/or Chinese.
- Many multicarts have an unusually high number like 200-in-1, 777-in-1, or even 99999999-in-1.
- Most of them use a menu system, although multicarts containing 4 games or less (sometimes considerably more for Game Boy multicarts) are sometimes reset based.
- The carts typically don't hold up their promise, meaning the last few games could be duplicates of the originals.
- With earlier cartridges, the lower the number of games listed often indicated a better cartridge. Lower counts like 4-in-1 often contained larger, rarer games, and sometimes pirate originals or hacks.
- The copyright notices are usually removed from the games. Occasionally the logo is removed as well.
- NES cartridges use "mappers"; mappers are special chips used to enhance later cartridge releases. There are over 100 mappers in total, but multicarts often only support mapper 0/NROM (which are cartridges with no mapper at all) and mapper 4/MMC3 (which is used in some late 80s - early 90s releases).
- Some multicarts also feature mapper 3/CNROM games. Usually there is no support for mapper 3 on the cartridges; the games are heavily modified to run on the multicart's own proprietary mapper.
- Games like Tetris, TwinBee, Dr. Mario, and Arkanoid are often cut down in multicarts to turn them into mapper 0 games (see above). This causes some graphical glitches, but doesn't render games unplayable.
- As they are developed for Famiclones, some multicarts will not work properly on a real Famicom, if at all.
- DIP switches that can "alter" the amount of games on it, although the extra games are usually repeats.
- Many more recent multicarts are much larger (16/32MB) than usual, and can contain approximately 150-400 different games on them. Certain ones will not work on a real Famicom.
- On multicarts for all other systems, the games usually retain their copyrights. Known exceptions include some older Mega Drive multicarts.
- Atari 2600 multicarts are usually reset-based with no menu system, and can have anywhere from 4 to 128 games (the latter meaning the player would have to ridiculously reset the console 128 times to fully navigate the menu). A handful of later cartridges instead had physical switches sticking out of the cartridge itself to select each game.
- SNES multicarts usually contain about 7 games without repeats.
- Mega Drive multicarts are similar to those for the SNES, except some of them contain repeats.
- Some larger Game Boy multicarts are twice as tall as standard carts to accommodate the extra games.
- Some Game Boy multicarts don't have a boot-up menu at all, and instead, employ a physical button on the cartridge itself which resets the system and cycles to the next one on the cartridge.
- Game Boy Color multicarts have backwards compatibility for the Game Boy. However, GBC games that don't work on a Game Boy are exempt from this.
- Game Gear multicarts sometimes have either a small number of games made for it or Sega SG-1000 ports.
- With bootleg GBA multicarts, most (if not all) of the games included are for the Famicom/NES. These kind of multicarts were created with PocketNES, a free NES emulator for the GBA.
- GBA multicarts often list most of the games in alphabetical order, apart from games beginning with one or two certain letters which appear earlier in the list.
- With GBA and recent Famicom multicarts, there are normally several larger Famicom/NES titles included among the frequently included games.
- Nintendo DS multicarts typically include DS games exclusively and many of these contain at least 250 different games. Some of them have additional menu options for games from other systems (NES, Game Boy, etc.), but clicking on them does nothing.
- Many DS carts actually feature a micro SD card shoved inside the plastic (or sometimes just covered up with a sticker). They are likely based on Flash Cartridge hardware.
- There is one known multicart for Nintendo 64. It features the original Mario Party trilogy and fifteen NES games, which seem to be running on an unidentified homebrew emulator.
- While not actually cartridges, many multigame compilations were released for disc-based systems like the Dreamcast and Playstation 2. Almost all of these discs exclusively feature various Mario games for NES and SNES, and are often branded as Super Mario All-Stars collections.
- Some portable DVD players are bundled with a disc featuring NES games (called the Game VCD) and 2 controllers, The Game VCD claims to have 300 games, but there's only a small number of unique games.
