I've been reading https://www.assemblergames.com/forums/showthread.php?49263 I have all the supplies listed until I started to map out what needed to be done here - http://www.gnys.se/da_bear/famicom/avmod/DSC_9148.jpg
My motherboard looks different and it's difficult to find what I need to do - could someone give me some information? I've supplies pictures of my famicom below (it's a (HVC-CPU-007); H6863099 - not sure if this is helpful info or not)

At the bottom there are photos for most revisions (including yours), so try that. :)
Dont be afraid, yes it looks differeent, but on your picture you need to add a capacitor between pin 20 and 22. So turn your board around and count pins to find out the correct one and solder there.
