Ok, so I got to the ATM Scorpion fight in the Nibel mountains. Spotted problems right away, which I am now reporting.
First, the "Area" for the battle is showing the Corel Prison, and NOT the Nibelhiem Mountains.
Second, the text with Barret talking about "That damn thing showing up again" (though with more "$%#&^!") appeared even though Barret was not in my party (this earlier aspect made sense when the fight was in the Corel Prison where Barret was a 'locked' party member and sure to be in the fight, but it doesn't work here). That said, changing the name from "Barret" to "Cloud" would fix 'most' of the issues with that there (as Cloud is the party leader at that point with the fight being moved to the Mountains), and would be annoyed at it showing up as much as Barret would be.
Third, the Shinra mooks who show up on the map near the ATM Scorpion do not show up in the battle itself.
Fourth, you may need to raise the ATM's level and stats, as with it being the "Prison" battle moved elsewhere at the moment, the fight does not take long at all, and is not very difficult/challenging. :shrugs:
Edit; Also, on a seperate note, when I went and did Yuffie's scenario with the stolen materia and all that, I got a chance to grab all the pub fliers and then talk to the bar owner. One of the items he handed over however is notable due to it being spelled as "X-Mine". Not "S-Mine", but "X". Probably a misspelling (or the name of a much earlier item that was changed and the name of the item handed over by the turtle's paradise pub owner not being changed with it), so I had to say something so you know about that Sega.
Second Edit; When I got Cid, the text for his Innate ability showed something very different from what is listed in the "Readme" text file. Also, the "Readme" talks about how the Fort Condor materia shop has had its contents changed earlier in-game, but I'm on disk one, and that has not actually happened.
Third Edit; Speaking of issues with "Innate", Vincent does not gain MP as is stated in either the readme or the game. I'm not sure if his "Innate Ability" is actually doing anything at all to be honest. I'll test out Cid and Cait Sith in a few hours.
Also, in the Temple of the Ancients, you're gonna have to mess with Tseng's text box when he tells the party he doesn't need their help, as the text-box breaks with its current size.
Fourth Edit; Cait Sith has Vincent's MP regen, which means that if this is 'right', then the in-game and readme descriptions for Cait Sith (and Vincent's) Innate Ability need changed and updated. Cid's "Reactive Guard" Innate Ability has shown itself to work like the 'in-game' description says it should, but the readme text file for Cid will need updated here with that (as it doesn't show what Cid's Innate has been changed to at all).
Fifth Edit; Sepiroth's line of "Listen Well," before then going on about the ancients in the Temple of the Ancients is unreadable. The text box is far too small for the text being displayed there. The first "Wake Up" line is somewhat too small as well, though not unreadable like the "Listen well" bit.
