Perhaps the most annoying aspect of seed 92 manipulation is the process of obtaining seed 81 and getting that coveted 10th-step encounter. In the default scenario, you have to hard reset between each attempt. For most consoles, this requires upwards of 15-20 seconds of the console being off between each attempt. In order to simplify our lives and reduce aggravation, the following method was devised. I'm honestly not entirely sure about everyone who is responsible for this, but I am almost certian that Myself086 was involved.
The first step is to get to the so-called Mage Room. There are essentially two options, depending on if you already have late game saves available or if you are familiar with the Any% NoCW route:
The first option is to simply do a standard Any% NoCW speedrun until you get to the Mage Room. For the purposes of setting up the glitch room, the inventory is completely irrelevant, so you can largely ignore that aspect of the route. It is, however, very important to put the black chocobo in the correct location as that is how you access the room.
The other option is to start with any late game save (one with one or more airships and access to both the Overworld and the Underworld). Once you have loaded that save, you will need to verify all of the following vehicles are in the proper location.
From here, all you need to do is enter the glitch. After entering the main hall of the castle, head to the right stairway and go up the stairs. This is the third screen transition, so you are now on floor 3. Repeatedly go down and back up this staircase until you reach floor 63. At this point, head in between the two shops into Cafe HOWDY! Exit the room the same way you came in and you should enter the glitch. Keep walking left until you enter the Mage Room, which should be fairly obvious due to the presence of numerous well-known mages.
Once you're in the Mage Room, you simply need to execute the following set of maneuvers:
Congratulations, you now have a Glitch Room save that you can probably use to get to seed 92 slightly faster than you were able to before.
Using the Glitch Room is actually very simple. When you're ready to begin a run, load the Glitch Room save and (assuming you're facing downward) press A. Immediately reset the console.
You now need to press A on the title screen at the appropriate time to get seed 92. This apparently varies slightly depending on how quickly you reset, but it will generally be around the second or third note of the song. For me, it's approximately 2.75 notes in. You will probably need to practice this timing a little bit before you get it down.
Of course, you still have to successfully hit seed 81 to make this all work, but now your downtime between attempts is greatly reduced.
There is one major caveat you should be aware of: save wiping.
When using the Glitch Room, there is a chance that the game will completely wipe one or more of your save files. My console rarely wipes anything, but others have reported all their saves being wiped (which makes the room pretty useless). More typically, it will erase either only save 1 or both saves 1 and 4 (and even more rarely save 2). For this reason, we recommend keeping your seed 223 file on save 3 (as it appears to be the safest), and your Glitch Room setup on save 2. (For extra safety, if you don't need save 4 for anything, you can save the Glitch Room there too. I've had the Glitch Room wipe only saves 1 and 2 before.)
