As I've spoken to other people about this in other threads regarding the same question about Nintendo 64, praise the heavens and the creator of whomever actually gets it to work/if they get something to work. "IF" being the keyword. Right now the closest thing they've got to work is running Nintendo 64 at 30% speed.
@zear himself specified that any work further from here would take at least a year of extremely knowledgeable programmers spending 40 hours full-time a week to do so, with a huge possibility at the end of that year......programmers saying, sorry we still couldn't get it past 30% speed.
Dude, I was so dedicated to getting Nintendo 64 to work, that I even started a thread asking if I could somehow upgrade the hardware or CPU in order to get it to do what I want. Ha ha! What a dumbass, right?
So, keep your fingers crossed and maybe one day it'll happen. However, don't buy a zero for those reasons. I'm trying to come to terms with this myself.
As long as we can at least get the TV out/HDMI feature working
