1) i was doing some reading on tips to beat Emerald Weapon and it mentioned using Knights of the Round in conjunction with Mime and W-Summon (and equipping a Gravity Materia for 9,999 damage each attack). call me an idiot, but i have no clue about either KOTR, W-Summon or Mime. i haven't encountered them in my journey so far and i think i am pretty far into the game - about to jump into the North Cave to go after Sephiroth, right after I killed Hojo and prevented the Sister Ray from being fired. did I miss these Materias along the way, or do i still have further to go before i find them? isn't the main storyline almost over? i hate that feeling of missing a bunch of stuff that i can't go back to

(like the limit breaks for Aeris - i exchanged the Mithril AFTER she died, of course... d'oh!!)
2) how the hell did anyone find out to morph the Ghost Ship in the Underwater Reactor area to get the Guide Book that you give to the gentleman in Kalm?? i really would have never had any clue about this unless i read these tip pages. is there some clue i passed along the way that would hint about getting this item? i know after I beat Emerald and Ruby Weapons i get the other pieces that this gentleman wants, so at least i'm on the right track but man, i'm still amazed someone figured that out

3) i defeated the original Weapon above the Cosmo Canyon area and finally have gained access to that weird jungle area. i'm not looking for a spoiler, but could someone prod me in the right direction in this area? i already got Vincent's weapon from the carnivorous plant, but i can't seem to get further than this.
you know what's great about this game? i thought i had beaten it years ago when it first came out on PS, but now, going back through it on the PC, i realized how much i missed the first time and surprisingly i DIDN'T beat the entire game. so from here on out, everything is new to me. this game still stuns me with its depth and playability.
anyways thanks for any responses!
