Slaanesh, you rock! I finally took the plunge and tried this one out - I have so much going on I only now had a chance to really try and wring this one out.
This kicks dingux-2600's butt!
This is way better, and much more user friendly, I think.
But you might mention to people it's easier if you put Stella directly in your /usr/local folder, and not usr/local/emulators - because the first place it looks for roms is usr/local/stella/roms.
I like the user interface much better, though. And there's more stuff to wank around with to fine-tune some games, lots of settings available.
This is truly a great piece of work, thank you!!
P.S. no diss intended to ZX-81, dingux-2600 was good at the time, but this Stella port just beats the pants off it, that's all there is to it!
