A new thread needs opening, WatashiWaZero, for these type of bugs, because most of them are definitely not Reunion related. They do need reporting, and many of them I will try to fix, but they need to be in a separate thread and then they can also be added to the bug database (not mine - White Wind's).
Not sure that one can be fixed, though...

One of them is just to confirm what Galm posted earlier. The buttons are swapped. This is probably an easy fix for you though.
Going back to our conversation about gil being capitalized or not. You're sticking with not capitalizing it, and I don't mind, but then you capitalize it on the loot screen when the original game had it on lower case. I can see why it would be upper case in the bottom right box since it's the only word, but the other two boxes should be lowercase. This is all for consistency sake.
One of the other pictures is the transition to the FMV. As noted in the description, this probably cannot be fixed, and I'm 99.99% sure you can't. Just wanted to note since it stood out to me.
Last picture has to do with what I said and your response quoted above. It shows you what I said earlier with the models not getting back up after being knocked down. There you can see that the second Dance is about to be cast by the Maul Dancer (I got the enemy and skill name for you this time), and the team is still on the floor. It actually has something to do with Reunion, most likely the models again. I uninstalled Reunion and played the game vanilla, and tried to replicate the bug, but to no avail. After I reinstalled Reunion again, I can replicate this glitch with every battle against Maul Dancers 100% of the time.
And finally, no pictures for this error, but on the map fship_23, when you first steal and get onto the Highwind, Tifa is seen on the bottom left of the map. As the camera pans/shifts upward to show the rest of the area, Tifa suddenly teleports to where Cid is standing and walks towards the middle. You can probably fix this as the error is similar to the one you fixed for how Tifa enters the map in the initial Avalanche meeting downstairs (mds7pb_2 I think)...
===========
I know I probably come across as nitpicky at this point, but I'm just trying to contribute what I can to this project. It'd be nice if you could doubt my reports less than you do now.
Also, wouldn't it be cool to end Reunion on R07?
