FFVI help about the "Veldt trick"

Okay so I reckon some of you are familiar with the way to manipulate encounters on the Veldt (I just read about it in a FAQ). I’m talking about how what you encounter is a random of seven from a certain group, then it goes on to the next group, and so forth in order. Random battle from group 1, random battle from group 2… etc. (more explained in this FAQ http://www.gamefaqs.com/console/psx/file/562865/13573 )

Now it says that when you save and reset, it adds 13 to what you last fought… that’s not happening for me. I tried making sense of it possibly skipping groups I haven’t encountered, but I noticed after different times of fighting Flans and saving, it took me to completely different random groups, not adding 13. Not adding any specific pattern either. I’m playing the PS1 version from Anthology. The battle order trick works alright, but the save/reset/load +13 trick is not. Does this not work in the PS1 version? Am I doing it wrong? I mean, I tried saving and resetting as I get an encounter to see if there would be a pattern when I next load, if it would stay the same or jump 13 or jump some other number. But nope, completely random.
Also tried with the memo file.

So is there any way to manipulate it in the PS1 version?

oh whoops, sorry meant to post this in Classics.

I’ve never heard of this trick, I thought tricks like this only worked on the early cartridges… But im not 100% sure man, you may want to look up some info on what the early cartridge releases have over the latter releases.

Makes me wanna ‘release’
