I would like to ask you some advice about creating SNES custom/repro PCB.
I'am looking for to avoid my future errors when I making "Router" of all tracks.
I'am using EasyEDA tool to design my PCB.
Always not sure about what width of tracks (thickness) that I have to do.



What clearance to respect end so on...
I always trying keep about 1mm for all GND and VCC (5v)
But about other tracks i'am not sure and dont really know what is the tolerance that I have to respect and for what component.
So I reduce, reduce... my tracks width to till get my Router worked

I'am sure that is not very good to do

If you can give me some advice, please, of max/min tolerance to keep absolutely for some special tracks or components.
PS: Hope that my English is enough clear to make you understood of what I want to tell

Thanks
