Question: Multiplayer Game Boy / Color / Advance Couch Coop Setup in Launchbox?

[totoro]

There seem to be some options to play Game Boy / Color / Advance Link supported games on one PC:

 

Is it possible to boot up supported games with Launchbox directly with 2 or more screens in fullscreen, with all screens next to each other so I could have a splitscreen-couch-coop session instantly? I guess this should be possible with some AHK-work involved...?

Alright, at least there is a pretty easy solution for Game Boy / Color 2player games:

So you can add another emulator, name it to something like "Game Boy Multiplayer Option" and point it to Retroarch, select tgbdual_libreto core.

I tried some games and it seems to work really well, exactly what I´m looking for - handheld multiplayer splitscreen action on one screen!

Now, it supports only 2 players, but there were some 4 player games as well, which need to be handled differently.

Also some games might not work, "Revenge of the Gator" didn´t seem to run the multiplayer mode, but I remember it was very picky on original hardware too.

So the request is still open for:

- 4 player Game Boy / Color games

- Game Boy Advance

Other handhelds come to mind, which would be cool on one screen:

- Nintendo DS

- Sony PSP

So I´m still looking for some nice booting options.
