Hi, I've been waiting for an English Patch to appear for a long time too. I don't know anything about coding and all those stuff, but I hope I can somehow help by reporting errors and glitches seen when playing the game :D
1) When opening treasures, it's all garbled, but at certain worlds(Eg: Atlantica) or certain chests, it's translated.
2) When villains are gathered at Hollow Bastion talking, the subtitles are garbled.
3) When fighting Ursula for the 1st time, when firing magic towards the cauldron, it doesn't react thus causing the boss fight impossible to end unless restarting the game with the original ISO and fight her then save again and restart with the patched ISO.
4) When you're in Accessories shop in Traverse Town, upon exiting the shop the exit via door it says "Third District" instead of "First District"
5) (Optional cuz I'm not sure if it's necessary to see this as a mistake) After downloading the .ald files, I've found out that there may be missing files (or maybe just named wrong). For an example, for Traverse Town, tw22.ard and tw24.ard are missing and for Hollow Bastion, pc14.ard is missing.
6) When going to the Jungle Cliffs from Bamboo Thicket, it occasionally writes cliff, otherwise it's garbled.
7) After doing the "checking ghost in order at the tombstone" with the mayor, the dialogue with him is garbled.
8) A lot of items like synthesis materials are mistaken as equipment when obtaining them from chests (Eg: Obtaining an Orichalcum should show a sphere beside it, but instead it showed a ring beside it, and Wishing Star is mistaken as a Cottage)
9) (Save/Load game data) location name aren't entirely displayed. (Eg: Evil Playroom is stated as "Evil Playr")
10) Oogie Boogie boss fight has the same problem as the Ursula boss fight. The system doesn't automatically pushes the trio onto the roulette thus battle cannot be ended.
11) 1st dialogue with Wendy after getting Fairy Harp is unfinished.
12) The dialogue with the Moogle in the Accessories shop is bugged.
13) Every object that's obtained in the library is unnamed(including books and objects from chests), but the symbols are correct and are translated.
14) When obtaining Emblem Pieces, it has the same situation as #13
15) When asked helping Pooh to get honey, the options are mixed up.
16) When Tigger first arrives, there's a slight hang.
17) After getting Divine Rose from Belle, the next dialogue from her is garbled.
18) The 1st dialogue of all princesses besides Aurora at the Castle Chapel are garbled (before fighting the Behemoth in Dark Depths).
19) One part of Leon's dialogue in the Library is garbled.
20) Yuffie's dialogue in the Library is garbled.
21) Every time after loading a game, the key image beside the "Attack" bar is far right instead of being inside the bar, thus the bar expands all the way there.
22) The dialogue from the moogle that gives Sora Encounter Plus is garbled.
Other mistakes have been stated by Hellbringer616 so I'm not gonna repeat them for your (hopefully) convenience. I am currently @ Hollow Bastion. I'll report more along the way by editing this comment.
Thanks a lot for the awesome people who have contributed to this project. Thumbs up (Y) ><
