I'm looking for the ultimate all-in-one Nintendo handheld. This should best enable native Wii / Gamecube (with original hardware) and additional consoles via emulators such as NES, SNES, GB, GBC, GBA, N64, DS and possibly 3DS. Is there a similar handheld by chance or will it still appear?
The following features should also be available as best as possible:
Simple software to which you can simply load ROMS with the PC using drag and drop
A Wi-Fi connection for software updates, cheats, etc.
Enough storage space for many games
A very good display (good colors, high brightness, contrast, resolution, viewing angle, etc.)
A high quality retro case, which is not too big
Good user interface and simple and quick usability (especially when switching between consoles)
Good speakers
Good battery
Send me links if you have something.
There's no such thing. Only in the PC.
Uff! It's a pretty difficult thing. Such a prebuilt system will be difficult to find.
But you can take a Raspberry Pi. Heise has it as a bundle with a HAT extension that you can play with like a controller. Then all you need is a housing and the right emulators, but they are usually free anyway. You can use a power bank for the battery.
Heard of retropia?
the thing can emulate more than 30 consoles.
handheld version:
DIY of course.
But keyword retropie.
I think he wanted a finished, buyable product. That there's no such thing.
