ChampGames and ChampProgramming hired me to debug some of their games. I wasn't given credit but they used Turbo C and Turbo Assembler like most other DOS based video games companies.

They called it Kong or ChampKong, but Nintendo decided to sue them anyway. You see originally Coleco had the video game console rights for Colecovision (It was the main game bundled with each Colecovision) and then the Atari 2600, Mattel Intelivision, etc. Then later Atari got the computer rights and made it for their 8 Bit series Atari 400/800, and the Commodore 64, Apple 2 under Atarisoft. THe problem was coleco and Atari were fighting for the right to Donkey Kong and other games, and Nintendo owns the rights from the arcade version and made one for their NES (Famicom) system. Well it turns out Nintendo had only sold the right to use the Donkey Kong game to both Atari and Coleco and later on revoked it and made their own version. Atari had tried to make a PC version of Donkey Kong but Coleco sued them and then Nintendo dropped their license to use and sell it.

So of course ChampGames made a Donkey Kong game called Kong to fill the vacuum. It had enhancements that the original did not for example that you could unlock by paying for a license. IIRC it was shareware you could play it for free, but if you paid for a code it would unlock features in the game to make it better.

But just like Nintendo took out the Crazy Kong, Donkey Monkey, and other copycats they also took out ChampGames and their Kong. So my job was gone.  Video games like Sega's Congo Bongo were like Donkey Kong, you got this guy climbing stuff to get to a big gorilla at the top but in Congo Bongo they made the steps 3D instead of 2D, and instead of Mario they had this Safari Joe guy, and instead of barrels he throws coconuts.
