Don't know if anyone still cares about this pack, but it has been my favorite for a long while. That is why I have decided to continue it privately. If anyone still prowls this thread let me know if you're interested in me making public contributions in the future.
Awesome, I would love to help as well, I've been trying to get into pixel art and I think this would be a good way to start. if you haven't already I can start with tinkers and work up my way from there
(I have the old R4 pack from a different forum page since this one's link is broken)
