2FM has a patch that's essentially 100%. Your 1FM is basically done, just with some off item descriptions in the shop, which isn't that bad. Your patch also doesn't seem to have the bugs I listed, and also has the widescreen hack. Thanks. Either way, I completely understand. Issues are issues, and I hope you work through them.
If you don't mind me asking, have you fixed the Gigas Shadows not spawning, the "Getting stuck at the Final Door after talking to Kairi" and the End of the World bugs? Currently with the patch I'm using from this thread, Gigas Shadows do not spawn. If I go to the Bizarre Room in Wonderland, the room just stays completely empty, with a keyhole graphic replacing the doorknob model. Also after talking to Kairi in Hallow Bastion, there's supposed to be a new cutscene with Riku, however with this patch, the scene does not load and merely places Sora at what is assumed to be the same location, unable to escape. And finally for bugs I've noticed, after getting to The End of the World and fighting in the first fight, it seems that the collision data for the walls does not unload, leaving one unable to continue. Glad to know that the version there is slightly more updated though. It'd be nice to be able to read the text in Hallow Bastion and Traverse Town again.
Playing through it now, it does appear to be mostly complete. You may want a guide just in case. Traverse Town and Hollow Bastion don't have any text, just garbled up messes of the font, and some other things appear to be off. (Such as description for some moves containing strings of text from others). It also tends to crash a fair bit. But it's complete enough to play at least. Hopefully it gets the same treatment that KH2FM did soon.
