I'm loading every TM2 from the PSP version of FF4 into memory, and writing them to PNGs right now. There's over 13k TM2 files, and 145 of those TM2 files fail due to an out-of-bounds error that occurs when trying to swizzle those textures. Thing is, I'm not completely sure those textures need to be ...

I've been writing a TM2 loader in Rust for my FF4 clone project, and it's been going pretty well. There's over 13k TM2 files in the PSP ISO of FF4. I'm still running into a few bugs and compatibility here and there. I'm not sure how portable my TM2 loader is for other games. I've done some digging o...

I've been wanting to make my own top-level, random-battle RPG for years now, but I didn't have the necessary assets. I was inspired by FF4 because its game loop seemed simple, yet fun. I've also wanted to learn more about how people figure out already-compiled games, and make mods for them. Then, I ...

I think I can help. I started a project back in 2020 where a friend and I attempted to write an open source clone of the PSP version of FF4 which uses the .tm2 format for its textures. That game has a lot of .tm2 texture files that have LZTX compression built into them. Ironically, I dug up that old...

Hey all, Does anyone have any info deciphering the assets for the .HACK games? I've found public Google Drive repos that have OBJ rips of these models in their T-pose, so I've got the feeling that people have been able to decipher them over just grabbing the data as a 3D "sceneshot" using ...

I've been trying to figure out the tile map config file format, and I think I'm getting there... These files are all the little .cn2 files within the map directories. It looks like the the first 2 bytes of the file is the width of the map (in tiles), and the next 2 bytes is the height of the map. If...

After a few more days, of researching and trying different things, I figured it out! I ended up creating a post over at ROMhacking.net, and got a helpful response that helped confirm a few things that I wasn't too sure of. Here's the link to that post along with pasted code, and a link to the open s...

Hey everyone, I've been learning Rust, and I wanted to try my hand at rebuilding at least part of FF4. To do so, I'd like to be able to scrape at least all of the graphical assets from the PSP ISO version of the game. I have a physical copy of the game, the ISO, and I've been able to extract many of...
