Completely new to this. I want to gift a handheld to my cousin's kids with some old classics installed. Initially I tried couple emulator apps for android phone (both from app store and FDroid) with Ted Woolsey's FF VI edition and none of them worked and after trying to problem solve it for some time and not getting anywhere just gave up. So I came with this handheld idea. Are there any handhelds out there which support freeware digital ROM/ISO files and which just work? Is this a market segment which exists?
