Hm.. I tried the 800 * 600 resolution, it lets me see "a little" more of the prompt buttons, but at least with Anxious Heart (which is what I tried for this), scrolling through the agreement text still won't "activate" the Next button.. Not entirely sure why..
As for the polygon thing for FFVII.. That's a shame.. D: I know FFVIII's character textures can be altered without changing the actual game and mounting new ISOs and altering the Steam files.. I'd just rather not modify those files from where they are. (Though to be fair.. I also have the PS4 version.. Which I seem to be considering my "primary" save/playthrough..) That said, from what I've seen of character model mods for FFVII, only the field ones seem to be a full set (either FFVIII style tall, or the chibi original look).. While the battle character models are.. Not full sets, they end up looking rather jarring by how different they all look. There doesn't seem to be a standard "one style for every in-battle character model".. So most of them end up looking so very out of place within the base game.. :/ I'm a fan of consistency, y'know?
