Materia Overlord not working?

[Taletta]

Is anybody else having issues with Materia Overlord not working? I've mastered every single materia besides that whole Underwater business, and I have at least 1 copy of Master Command, Magic and Summon, and I've mastered 2/4 Enemy Skill materia so far. What the hell am I doing wrong?

I got mine literally just now 1 minute ago. The way I got mine is I had mastered every single one of my Materias first. Even my 4 Enemy Skills were all mastered before I even mastered the rest of my Materias. I then went to defeat Emerald weapon. I traded the Earth Harp for the Master Command, Master Magic, and Master Summon. I then got in a random battle right outside Kalm. After winning my first random battle it gave me the "Materia Overlord" Achievement. I can confirm that you don't need to learn some last enemy skill or anything like that as I had all my Enemy Skill Materias mastered before I even mastered all my other Materias. I hope my post helps some of you.

I spent a lot of time farming AP in the Norther Crater in order to master all my materias, I defeated Emerald Weapon and got the 3 Master from the Kalm Traveler quest, 2 enemy skills completed and got even the underwater materia....and yet I didn't unlock the achievement.
I was quiet nervous and I've got here reading all your messages to find a solution, but none of them worked....and in the end, even if I checked 1000000 times to have all of them mastered, I realized that my Transform missed around 2000 AP, I always saw I had 2 of them and without checking closely I thought "ok, even this one is mastered", but I just had 2 because for sure I bought one by mistake, not because it was a double from the mastered one.
Meeeh what an idiot! After getting those AP and mastered Transform, achievement unlocked.
I don't know if that enemy skill thing is a solution, I had my Master Materias from Kalm and not sacrificing all my materia in Cosmo Canyon, so I don't know how to help about these things, but I report here my experience to tell you to check WELL your inventory, for dumbasses like me, 10000 checks are not enough! XD Bye bye!

The first Transform materia was probably picked up on the minecart tracks as you're entering Corel. Cait Sith comes with a second one partially leveled up when he joins your group.

I had the same problem. Mastered all materia within 50+ hours of gaming and the achievement just wouldn't work. After 2 hours of checking the list over and over again, I finally noticed that Underwater materia wasn't in my list anymore. I am 100% sure that I didn't sell it or something like that. I had the Underwater materia when I killed Emerald Weapon. Now it's gone forever. So this might actually be a bug in the game.

Old materia may be lost when you accrue enough materia to fill up your materia-inventory.

This achievement really irritates me, I know for a fact that I have all the materia and I did not receive this achievment. I've beat the game over 10 times back on PlayStation with 100% completion, just like I did this time, and I never got it... `bout through my computer out the window. Is there a way to still get it without restarting the game or modding it?

I say that the best thing to do is to check and re-check the materia you have, aside from that I am not sure what to say.

Actually I started playing around with a program called cheat engine and lowered Cloud's Level from 99 to 98, as soon as I leveled him back to 99 I got the achievement for some reason.

...Whoa, that's really strange, haha. I do not know a lot about FF7's core programming and how that interacts with Steam's achievement system, but... Yeah, strange.

Glad you got the achievement though!

Exactly the same situation for me.

When mastering Materias new ones are born and they seem to kick materias like underwater out of your inventory, try black chocobo, there's no other option then replaying.

In my case, I mastered the Enemy Skill materia (last one that I needed) without realising that I had just sold all my mastered All materia for the gil achievement. Reloaded to an earlier save, mastered another All materia and proceeded to finish up the Enemy Skill materia again to finally get the achievement.

Epic fail :D

[ThunderPeel2001]

Ugh. I have literally mastered every Materia in the game, but I didn't get the achievement. Please don't tell me it's because I made a couple of Master Materias at Cosmo Canyon...? Surely the same isn't so dumb as to not make note of the Materias I've mastered as I was going through...? :(

You shouldn't have turned your mastered materia into a master type. You need to have each type of materia mastered along with an enemy skill materia with all skills on it in your inventory.
You.ll either have to remaster the copied materia from scratch or use an older save from before you traded each materia to the huge one.
