You could play multiplayer Tetris that way. I think I saw it once in my life.
There‘s also an excellent Gameboy Color romhack of Dr Mario that supports multiplayer. Recently tried that out with my girlfriend and it was a lot of fun.
Edit: this is it for anyone interested. Looks like even the original version for the Gameboy supports multiplayer.
I played multiplayer Tetris frequently.
When you get lines, your opponent’s stack pushes a line with a gap up from below, except when you get a Tetris, which pushes four lines (with the gap aligned, so you could Tetris back and forth).
You had an indicator for the max height of your opponent’s stack next to yours.
Great game.
In 99 we had a sleepover and we’d all trade our best pokemon to one another and pulled the plug out before completion to clone the pokemon.
I have a real job now and do real business deals. Nothing I’ve done professionally has ever felt as official and business like as that one sleepover.
Maybe the real business deals would feel more official and business like if you could employ the pull out method with them too?
If only money transfers worked this way…
I send you money, cancel mid way, and now both of us have the money!
back in the late 00’s there was (maybe still is, who knows) an online service called “gamefly” where you could rent games. At the time the DS pokemon games would allow you to plug in a pokemon GBA cart and copy the pokemon from the GBA to your DS. So I would constantly rent GBA Pokemon games in hopes of finding something good on them to copy to my DS Pokemon game. I had it all scheduled out and everything. You could also wondertrade hacked pokemon or like really good pokemon online. I don’t remember exactly HOW you did it but I do remembering doing it.
Were there other uses? Yes.
Were they common? Well, just look at the GameBoy pocket. At the time it was designed (it released 7 years after the original GameBoy) there were a lot of people at Nintendo who wanted to get rid of the port entirely because it was barely ever used. They ended up compromising by using a different, smaller, cheaper port that needed an adapter to work with the regular ones.
Which was kind of a pain for some people because the GB Pocket and Pokemon both came out in Japan in 1996 lol.
Multiplayer tetris was fun! Whenever you completed a row, you’d send it to your opponent!
We had even one to connect 4 Gameboys and played “super rc pro am”, oh the nostalgia
Each player needed a copy of the game. Game Boy Advance had a bootloader that could receive data to run a multiplayer game with no cartridge.
