Yeah, I did exactly that. The game just black screens on load w/ no sound (though it does show different colors for the load game text as well).
Edit: I've also tried JP locale, english locale, deleting/renaming both img.dxa/img2.dxa and the openoffice file, and leaving the openoffice file be. Noone of it works.
Whoa!

i dont know what those img.dxa3 and img2.dxa3 files are or what their doing there but i dont have them. maybe related?
i believe i fixed the problem anyway, altho i only had it happen once and then never agin, so if it is a 'real' problem, i guess i fixed it? closest i got to 'the problem' (for sure) other then getting it once on a fluke, was trying to load the game via USB to a new laptop i have, but it was a simple case of 'don't try and load via USB' as all i had to do was wait forever and the black screen went away and the game proceeded with sound and video.
now includes finished new character graphics and all labeled!

took me forever to finalize the design of the new graphical style for the labels. heres a example of the finished thing ingame with the games new default graphics (attached to post as image)

and heres the new link for alpha 0.2: <removed> check later post
now includes some new 2F enemies as well. my time to work on this has been very limited, but i'll get some more tomorrow. been REALLY playing through persona 5 on merciless difficulty, im 75 hours in and i think im 50% done the game

but this weekend im letting my friend borrow my PS4 so TO MOD WORK I GO~!
also attached is the exact files to rename / delete / move so they arn't in the games directory. as of now on 3 different PC's, the mod always works. and i can't really think of why it wouldn't work. again, its still early into it, im going to be changing menus more, and a bunch of other stuff. i'll probably tackle changing the rest of the enemies first tho, but i got sidetracked on finishing up the new character portraits / labels so the player can easily see what characters use what elements, to really use the in battle charts.
final note: im aware some enemies charts may overlap. in the default game, enemies were already very close and overlapping somewhat, you just didn't notice as much or care because it wasn't important text like a chart being blocked because of it. as i update the enemies that are in the game with new sprites, i'll adjust things so the overlap doesn't happen anymore. (except for the intentional ones of 6 enemies on the exact same location) but for the time being, some charts in random battles may be hard to read due to enemy overlap i'll fix it i promise! and again, feedback is welcome, and i guess, anything not really feedback wise, but simply something you would like to see changed period, is also welcome! i'm probably going to look into having the colored gates be significantly more different between their 'open' and 'close' states, so their easier to tell if the games are open or closed just by looking. i felt when i first played it wasn't clear enough. thats a example of 'general suggestions' you could ask for me to hit as i pass over the games graphics.
