Hi all - I've been obsessed with this little game for a very, very long time, and I'm trying to learn the file structures to try to make it work. I've got the files broken out into the different formats from the disk, and I've pretty confidently identified the .md model files. The mesh files themselves I'm exploring with ModelResearcherPro, and this is what I've come up with so far. most models have multiple meshes embedded, and there's some things I have and some things I haven't figured out yet. I'm using the attached GSG03.MD as the example model, which Iam pretty sure is a robot broken into multiple bits. (There are some models for like a map model, and it's broadly similar.) File Start: Little Endian First long 26 00 00 00 Mesh Start 7x long or floats of header - this is different for each file, but very consistent in length. First long is an address pointer to the end of the vert section, 4 bytes after the vert end marker. Then 6 other ones? Next is what I'm calling a New Mesh Indicator, but probably has some other function: 3x 00 00 80 3F (read as 1.0 as a float?) Next long is the address pointer to the of end of the mesh total (eg. 74 05 00 00 -> 0x0574) then a null long, then a set of bytes that are a consistent header within the file but I haven't sorted them out yet (eg: 17 25 06 00 A3 9E 9C FF 3F 3F 3F FF 99 99 99 0C 40 00) (somewhat consistent between files, at least the same header format, read as: 17 25 06 00 XX XX XX XX XX XX XX XX XX XX XX XX XX XX. ) Then an unsigned int short for....something? doesn't seem to line up with number of faces, or a pointer, or anything like that, but it changes for each mesh in the file. It's bigger than the vertex count, but that's about all I know. Maybe a total number of objects to process, and you subtract out the verts? Then a mix of triangular faces and normals, maybe? Triangular Faces using unsigned int shorts as vertex identifiers (I think), and probably normal vectors? Not really sure how to break through this, the faces don't really align with anything resembling sensible geometry. Also, there's periodically very large shorts, like FB FF, that break the vert indexing. They one's complement into somewhat sensible vertex indices, but no other rhyme or reason as far as I can tell, and I don't know how to do that automatically. At the end of the faces section, there's a long of FF 00 00 00, which I think is an end marker. Then another short 29 00, then another short that's different for each mesh, then another null short. Then a Vertex Count Short (unsigned int). This one I'm fairly confident in, and it's reproduceable. Then starts a mix of Verts and UV and maybe something else. I don't really know if this is right, but it makes the address math work out: each point is 6 floats: ??, U?, V?, X, Y, Z. Then after vertex count of verts, another FF 00 00 00 end marker. Next is 6 longs, and the first is the one that the End of Verts pointer addressed Finally either a short and a null short, or a long, but a low int 24 00 00 00, or 36 00 00 00, and is the address of the end of mesh pointer. Maybe it's actually the beginning of the next mesh? Sometimes there's an empty mesh at the beginning or end. Not sure, but they don't have an end of mesh pointer; sometimes they have a few vertexes, sometimes not. I'll get to textures eventually, but I'd really like to figure out what the mesh format is first. Anyhow, thanks for taking a read! I don't really know what I'm doing yet, but I'd really appreciate any guidance you've got on this. GSG03.7z

Hi, I wanted to extract the weapons.lib file from the game 25 to life, i have a way to make it playable on console like PS2 and Xbox and also PC. no matter what program i try to use to open a lib file i always get an error. The reason i want to open this file to see what's inside and to experiment these in single player because i have a script that allows these characters to be playable in single play and i want to do a video showcase on my YouTube channel of all these weapons including scrapped weapons since nobody else has ever done this for this game. Here's a video of the custom playable characters in single player with MP weapons: WEAPONS.zip

Hello, I believe this is a good place to have this topic, anyways, I want to know how I can extract the models from the following 3 games: Monster Rancher 3 (2001), Monster Rancher 4 (2003), and Monster Rancher EVO (2006 in the states, 2005 in Japan). These 3 games are for the PS2 console, and I want to know how to open the .dat files of these 3 games. I'm willing to accept your wisdom, provided that you know what you are teaching me. I thank you in advance, and I also provided 3 screenshots, one for each of the 3 games, and all of them are Monster Rancher related.

love it or hate it Metal Slug 3D PS2 (2006). I just need to extract pak file so I knew there are 3d models of enemies and vehicles in the 2006 game but I couldn't extract it I used BMS quickbms https://aluigi.altervista.org/bms/metal_slug_3d.bms it only works only DATA file and the folder in the iso metal slug 3d ps2 doesn't have it! help please !

There are at least two types of i3d file formats, used within the .i3d files used in ape escape 3 and Rule of Rose uses .i3d files in .mdl files. I3D_BIN: Mesh ✔️ Bones ✔️ Skin ❌ I3D_I3M: Animation ❌ Tools: https://github.com/Durik256/Noesis-Plugins/blob/master/fmt_i3dg.py - Supports meshes. fmt_RuleOfRose_PS2__i3d.zip - Supports bones (made by Bigchillghost from xentax, reuploaded into reshax for quicker accessibility)

I want to rip from a game released only in Japan on PS2 called "Jigoku Shoujo Mioyosuga" developed by Compile Heart. More info for curious people on the game or franchise : https://en.wikipedia.org/wiki/Hell_Girl#Video_games or https://gamefaqs.gamespot.com/ps2/961167-jigoku-shoujo-mioyosuga I've extracted the files from the game and it seems most of the game data is stored in .PTD archives (other files are .PSS that are movies files). There are 11 PTD files and I don't know if they are encrypted or compressed. What I've noticed is that it seems there is a file index table named "PTDALL.PID" which seems to contain the location of files and data but I'm not very familiar with it so I'm not sure. Maybe with some bms script it will be possible to extract everything so thanks for the people that will be able to do this. Download link of the files : https://drive.google.com/file/d/1IIgGjkqZBM__VNdzehLaWAFwmuNUGckl/view?usp=sharing. The PTD files are in the DATA folder.
