When you were holding a red-and-white cube with four directions, four round buttons, and two short black bars to play Super Mario Brothers (Super Mario), Contra (Probotector), Teenage Mutant Ninja Turtles (Teenage Mutant Hero Turtles), Double Dragon (Double Dragon), Bomber Man (Bomberman), Kung Fu (Kung-Fu), Adventure Island (Adventure Island), Pac-Man (Pac-Man), Lifeforce (Salamanca)... during those years, you absolutely didn't know that the thing that could control everything was called FC —— Family Computer (shortened as Famicom or Red-and-White Machine, not today's KFC, etc.), at most it was just called a game console.
Of course, most people played games on something that wasn't the legendary Nintendo-branded FC (back then, no one cared about brands or companies; all plug-in yellow cards were simply called "game consoles"). What left a deeper impression on more people was the line from Donald Duck: "Little霸王, endless fun ah~", which was truly unforgettable!
With those piles of hundreds, thousands, and even ten-thousands IN 1 yellow boxes, childhood passed by like that. Most of my game cartridges lost their yellow shells and only had the circuit boards left, but I could accurately do "see the board, know the cartridge". I could remember what games were on each cartridge and their corresponding numbers.
If there was a 100 IN 1 game cartridge containing the following games back then, I would be willing to trade a year's worth of lucky money for it. The experience back then was that if you had a 10000 IN 1 game cartridge, it might only have ten games, each game repeated 1000 levels, and they all had different yet very attractive names. So when buying cartridges, you couldn't just look at the big number in front, otherwise, you'd cry once you got it home (it seemed that trying before buying wasn't popular back then).
Now, some foreign websites have embedded them into a webpage using Java as a 100 IN 1 collection. I tried a few classics, listening to the sounds brought back from memory... The difference is that the controller has been replaced by a keyboard, and I'm far from having the skills I did as a child.
