Did you try those links that I listed above? I know the links on the first page are long since dead/bugged but I can confirm that these links all still work; Crazycatz's are the first two, gledson's is the last. And no, since there's been no updates posted, no news on any bug fixes or changes, sadly. Speaking of. Did you ever get around to fixing this during that holiday? Didn't want to pester you too often, but I think it's been long enough for me to ask again. There's crashes in both of them in different spots; text alignment problems that don't effect gameplay but look bad, I *think* the Ursula boss fight is still bugged in Crazycatz's patch (unable to lock on the the cauldron), and I remember some people saying way back that at some point they'd trigger a cutscene in Traverse Town and, once it ended, they'd be teleported to the big Kingdom Hearts door at the end of the game. I never finished my playthrough of gledson's build because my college classes started back up and work took up more of my free time, but comparing the two patches on a file-by-file level, gledson's at least has Traverse Town and Hallow Bastion included.
I've only ever tried running the modded game over USB but maybe you could try different discs? Cheaper-made discs that aren't burned correctly may not work as well. You have to remember also that the KH1 patches, no matter who made them, are in varying degrees of completion and so some issues will persist until they're properly finished, if ever. I know that's not a lot to go on, but I hope that helps a little.
I sent him a PM on Youtube the other day but he hasn't answered it. You can if you want to but I don't want to pester him with the same question. It's not that important.
Absolutely. There's also the audio and texture tools on there if you wanna play around with them as well. Different download files, but up there. Edit: Speaking of; I did a lot of digging last night and I found a thread where people were talking about where sounds were stored in models (this was before Crazycatz00 formally released his sound tool). I know that people have modded the Re:CoM-era Organization members to have their English voices somehow but as far as I can tell, you aren't able to do that with the VSB tool, can you? I know the more experienced people have long since abandoned this thread but on the off-chance someone passes through, reason I'm asking is because I wanted to change around some of their lines for personal use. Since they're the same file format (though different versions if my reading is right) I should be able to do the same process to edit KH1 Sephiroth to give him his KH2 audio. I may try reaching out to KHDecoder on Youtube since they seems knowledgeable on hacking these games but whether or not they reply... Eh.
My bad; totally forgot about that. Crazycatz00's site has all the programs needed, since he made them. The KH1_ISOmaker.exe mentioned in the OP is in the ISO Maker download file, under the Kingdom Hearts 1 header on his page.
Clicky. That's the Google drive folder that the first post talks about. The rest of the directions should still apply. Here's the cutscene files. Should also mention that gledson999 was making an updated, slightly different version that supposedly fixed some of the bugs of the original translation patch before he went silent 2 months ago. If you have issues with Crazycatz's version, give that a look. Sora here also has a version of it floating around but I don't know anything about it as far as bug fixes or changes.
