Platform: Family Computer

Multiple early "black box" NES releases' cartridges produced during the console's US launch in Winter 1985 didn't use NES ROM chips, but rather Famicom ROM chips with a built-in converter. The 15 NES launch titles, and the only games known to have these chips, are:

•10-Yard Fight
•Baseball
•Clu Clu Land
•Duck Hunt
•Excitebike
•Golf
•Gyromite
•Hogan's Alley
•Ice Climber
•Kung Fu
•Pinball
•Stack-Up
•Tennis
•Wild Gunman
•Wrecking Crew

All of these games would eventually be reprinted with regular NES chips.

The robot boss of Sector X, dubbed "Spyborg" in the English version of Star Fox 64, is known as HVC-09 in the Japanese version.

HVC (Home Video Computer) was the model number that was used for Famicom (the Japanese equivalent to the Nintendo Entertainment System) hardware and peripherals. For example, the model number for R.O.B. (who in Japan was called Family Computer Robot) was HVC-012. Likewise, the model number for the NES Zapper (known as the Famicom Light Gun in Japan) was HVC-005. The model number for the Famicom itself was HVC-001.

Funny enough, in real life, there never was any NES related hardware whose model number was HVC-09.

The HVC Controller Test, a cartridge used internally at Nintendo to test Famicom controllers, contains a hidden Simon-style game, accessed by pressing B and Down on Controller 2.

In 2023, a webpage on Nintendo of Japan's website was created to celebrate the 40th anniversary of the Family Computer. One of the subpages is a list of nearly every game published by Nintendo for the system, including those released exclusively for the Disk System peripheral. The only other known official list of Nintendo-published Famicom games available is the Chronicle in the Japanese version of Super Smash Bros. Brawl.

However, the Famicom 40th Anniversary subpage omits several games that were included in Brawl's Chronicle. These include:
•Popeye, as well as its spin-off titled Popeye no Eigo Asobi, likely due to licensing issues with King Features.
•Spartan X (released as Kung Fu outside of Japan), likely due to the game being a license, as it is based on the movie Wheels on Meals.
•Miho Nakayama's Tokimeki High School, likely due to the game heavily featuring real-life Japanese idol, Miho Nakayama.
•Ginga no Sannin, a port of the home computer game The Earth Fighter Rayieza by Enix. It is not known why this game was excluded from the list.
•All re-releases of standard Famicom games for the Disk System (such as Super Mario Bros., Tennis, and Mahjong). The Famicom cartridge re-release of The Legend of Zelda is also omitted.

In addition to these omissions, while the Chronicle lists Mike Tyson's Punch-Out!!, the Famicom 40th Anniversary subpage instead lists the original Gold Version released exclusively in Japan, which did not include Mike Tyson.
