If anyone cares, here's how you beat Ruby and Emerald Weapons.
Ruby
The easier of the two. First, kill two of your party, and give the summon "Phoenix" to the one still alive (or if you are less cool then keep the people dead or just use Phoenix Downs). Make sure the alive character has the summon "Hades", and you have a lot of MP.
Normally Ruby will make members of your party disappear until you have one left, and you can't hurt him until this, however as you have two dead, he will put his claw in the ground, so you can hurt him, but he counters magic and summons with the spell "Ultima." First of all, cast "Hades" on Ruby. The use Phoenix (it heals Ruby, so use it on the claws). Now just abuse Hades, as it has the same effect as the status "Stop", until he dies. You can speed this up with KotR, but keep him Hades'd. Easy.
Now, if you didn't already, go get that Gold Chocobo from the man in Kalm, and head to the corner of the map (any will do, they are all the same). Enter the cave and get the KotR. Now here comes the big preparation for Emerald.
Emerald
Go to Battle Arena in the Gold Saucer and get W Summon and Omnislash. Then get Ultima Weapon (sword) by killing Ultima Weapon (enemy). Equip all this with Cloud and you can do the special battle. Win this and get the "Final Attack" Materia. Get this to as high a level as you can, and do the same for Phoenix. Now go to the underwater reactor and morph a ghost ship. Go to the old man in Kalm and get the Underwater Materia. Now, if you really want to prepare, get all your characters to 7777 health (get to xx77 health and use potions). Now for the first 5 minutes of the fights your character will do 7777 damage a lot of times. Make sure that Final Attack is paired with Phoenix (Emerald has an attack which does total number of materia x 1111, which is normally 9999, and it is on all). Keep KotRing and miming etc. and eventually it will die. Hurrah. Now get Master Summon, Master Magic and Master Command from the Old Man in Kalm.
Note: there are faster ways to do this, but if you haven't already managed to do them, this guide will make it easier.
Note2: for multiple Master Materias, get every Materia of that colour (mastered) and bring it to the corresponding large materia (except with Master Command, you don't need W-Summon/Item/Magic and you don't need Double Cut or Slash-All.
Any questions PM me, I am not quite a FF7 master, but I know a lot about it.
