I currently play most games thru emulators but been wondering whether it is worth it to get the Switch V1 version for handheld.
my plan would be putting the roms onto the Switch and then play handheld (is this possible?)
Playing when traveling, a few hours in bed before sleeping or cozy up next to the heather in the evening seems nice. However is it still worth around €300 euro for it, may I have your opinion on the matter?
I vote no.
Switch hardware in general is a much worse experience than emulation due to graphical limits, no save backups, etc.
If my understanding is correct, a used steam deck should be about €300, which will offer a much better experience for your switch games and play other games as well.
You can get a new one for $350 USD now and the hardware is easy to upgrade.
