I made a Varlife rule file for Golly. Golly may be more optimized than our current simulator, and Golly has copy and pasting, so I think this will help. https://www.dropbox.com/s/tmu02neaxz5hndt/Varlife.rule?dl=0
@ASCII-only Thanks! I couldn't create my own rules because I don't know how to, but I'll try looking it up for how to make .rule files if the VarLife one isn't sufficient
