Greetings all. I'm a fairly experienced ROM hacker who's done extensive work with Shining Force 2 (that thread is fairly inactive as I rarely post there, but my editor and knowledge of SF2 is much more extensive than in that first post).
Anyway, I decided to take a look at PS4, and in the course of a day I have cracked the text compression by following trace logs. Unfortunately, it's quite impossible to edit the text in a hex editor because of how it's stored (as I'm sure you guys know by now), but I'll probably write a script to do it soon. Would you be interested in the technical aspects?
Now I've decided to seek out PS4 fan forums to make sure I'm not wasting my time, and I'm quite impressed by the amount of knowledge you guys have about the contents of the ROM. However, it looks like there are still some things you haven't figured out that prevent a full PS4 hack from happening.
Is there anything else you guys want me to find? It shouldn't be too difficult. In addition, I may consider making a simple ROM editor for PS4 sometime soon, if I'm able to find most of the remaining missing information.
Thanks!
Edit: Oh, and for the record, my knowledge of PS4 is limited, so I'll probably need your help on where to find certain things.
Progress:
3/17/10 - I've found the enemy formation data. There are ~512 different formations (wow!), and each area can pick between up to 32 of these. Unfortunately, it's all compressed, so no hex editing here either. They seemed to want to compress almost everything in this game, and they still had trouble fitting it in the expanded cartridge.
3/18/10: Did some more searching and found enemy palettes and part of their animation data.
