how do people make emulator machines out of these things

or is it just a linux thing. it's great for video game graphics bullshit for everything else

all i wanted was a netflix machine that had composite out that did true 4:3 since they shut down the wii servers and no android box that has composite out can actually do 4:3

i know right, it's crazy, it's like we forgot old technology existed or something. like the burning of alexandria
