ABAB Soft was a publisher of bootleg Famicom games founded in 2003, and was the publisher of Hummer Team's games until they went out of business in 2005.
ABAB Soft's carts included official games and pirate originals developed by Hummer Team.  Their 4-in-1 multicarts generally seem to go under the Super Cool Boy 4-in-1 name using CB-xxxx IDs. However, not many of their carts have been found and the multicart menus that appear on their (now defunct) site all appear to be mockups. Despite that, according to Hummer Cheng, these multicarts was in fact released.

- On the website, the mockup screenshot of the multicart that contains Rings is the only known instance of its title screen. On the Super New Year Cart 15-in-1, the graphics for it have been removed so even if you attempt to access the screen through hacking, it only appears as a mess of tiles.
- In the source code for the website, you can find Handel Liao's name. Handel Liao was responsible for running Zechess. Given how Zechess started up in the same year ABAB Soft vanished, Zechess could be seen as a successor to ABAB Soft.
